a39f752 Miao Xie 11 September 2011, 14:52:25 UTC Btrfs: fix wrong nbytes information of the inode If we write some data into the data hole of the file(no preallocation for this hole), Btrfs will allocate some disk space, and update nbytes of the inode, but the other element--disk_i_size needn't be updated. At this condition, we must update inode metadata though disk_i_size is not changed(btrfs_ordered_update_i_size() return 1). # mkfs.btrfs /dev/sdb1 # mount /dev/sdb1 /mnt # touch /mnt/a # truncate -s 856002 /mnt/a # dd if=/dev/zero of=/mnt/a bs=4K count=1 conv=nocreat,notrunc # umount /mnt # btrfsck /dev/sdb1 root 5 inode 257 errors 400 found 32768 bytes used err is 1 Signed-off-by: Miao Xie <miaox@cn.fujitsu.com> Signed-off-by: Chris Mason <chris.mason@oracle.com> 11 September 2011, 14:52:25 UTC
0c1a98c Miao Xie 11 September 2011, 14:52:24 UTC Btrfs: fix the file extent gap when doing direct IO When we write some data to the place that is beyond the end of the file in direct I/O mode, a data hole will be created. And Btrfs should insert a file extent item that point to this hole into the fs tree. But unfortunately Btrfs forgets doing it. The following is a simple way to reproduce it: # mkfs.btrfs /dev/sdc2 # mount /dev/sdc2 /test4 # touch /test4/a # dd if=/dev/zero of=/test4/a seek=8 count=1 bs=4K oflag=direct conv=nocreat,notrunc # umount /test4 # btrfsck /dev/sdc2 root 5 inode 257 errors 100 Reported-by: Tsutomu Itoh <t-itoh@jp.fujitsu.com> Signed-off-by: Miao Xie <miaox@cn.fujitsu.com> Tested-by: Tsutomu Itoh <t-itoh@jp.fujitsu.com> Signed-off-by: Chris Mason <chris.mason@oracle.com> 11 September 2011, 14:52:24 UTC

fc61ccd Florian Mickler 10 August 2011, 10:05:20 UTC [media] vp7045: fix buffer setup dvb_usb_device_init calls the frontend_attach method of this driver which uses vp7045_usb_ob. In order to have a buffer ready in vp7045_usb_op, it has to be allocated before that happens. Luckily we can use the whole private data as the buffer as it gets separately allocated on the heap via kzalloc in dvb_usb_device_init and is thus apt for use via usb_control_msg. This fixes a BUG: unable to handle kernel paging request at 0000000000001e78 reported by Tino Keitel and diagnosed by Dan Carpenter.

de4ed0c Jarod Wilson 08 August 2011, 20:20:40 UTC [media] nuvoton-cir: simplify raw IR sample handling The nuvoton-cir driver was storing up consecutive pulse-pulse and space-space samples internally, for no good reason, since ir_raw_event_store_with_filter() already merges back to back like samples types for us. This should also fix a regression introduced late in 3.0 that related to a timeout change, which actually becomes correct when coupled with this change. Tested with RC6 and RC5 on my own nuvoton-cir hardware atop vanilla 3.0.0, after verifying quirky behavior in 3.0 due to the timeout change.

27a7b26 NeilBrown 10 September 2011, 07:21:28 UTC md: Fix handling for devices from 2TB to 4TB in 0.90 metadata. 0.90 metadata uses an unsigned 32bit number to count the number of kilobytes used from each device. This should allow up to 4TB per device. However we multiply this by 2 (to get sectors) before casting to a larger type, so sizes above 2TB get truncated. Also we allow rdev->sectors to be larger than 4TB, so it is possible for the array to be resized larger than the metadata can handle. So make sure rdev->sectors never exceeds 4TB when 0.90 metadata is in used. Also the sanity check at the end of super_90_load should include level 1 as it used ->size too. (RAID0 and Linear don't use ->size at all). Reported-by: Pim Zandbergen <P.Zandbergen@macroscoop.nl> Cc: stable@kernel.org Signed-off-by: NeilBrown <neilb@suse.de> 10 September 2011, 07:21:28 UTC

A single request to RAID1 or RAID10 might result in multiple requests if there are known bad blocks that need to be avoided. To detect if we need to submit another write request we test: if (sectors_handled < (bio->bi_size >> 9)) { However this is after we call **_write_done() so the 'bio' no longer belongs to us - the writes could have completed and the bio freed. So move the **_write_done call until after the test against bio->bi_size.

19d5f83 NeilBrown 10 September 2011, 07:21:17 UTC md/raid10: unify handling of write completion. A write can complete at two different places: 1/ when the last member-device write completes, through raid10_end_write_request 2/ in make_request() when we remove the initial bias from ->remaining. These two should do exactly the same thing and the comment says they do, but they don't. So factor the correct code out into a function and call it in both places. This makes the code much more similar to RAID1. The difference is only significant if there is an error, and they usually take a while, so it is unlikely that there will be an error already when make_request is completing, so this is unlikely to cause real problems.

9400775 NeilBrown 10 September 2011, 07:20:21 UTC Avoid dereferencing a 'request_queue' after last close. On the last close of an 'md' device which as been stopped, the device is destroyed and in particular the request_queue is freed. The free is done in a separate thread so it might happen a short time later. __blkdev_put calls bdev_inode_switch_bdi *after* ->release has been called. Since commit f758eeabeb96f878c860e8f110f94ec8820822a9 bdev_inode_switch_bdi will dereference the 'old' bdi, which lives inside a request_queue, to get a spin lock. This causes the last close on an md device to sometime take a spin_lock which lives in freed memory - which results in an oops. So move the called to bdev_inode_switch_bdi before the call to ->release.

0ec26fd Miklos Szeredi 05 September 2011, 16:06:26 UTC vfs: automount should ignore LOOKUP_FOLLOW Prior to 2.6.38 automount would not trigger on either stat(2) or lstat(2) on the automount point. After 2.6.38, with the introduction of the ->d_automount() infrastructure, stat(2) and others would start triggering automount while lstat(2), etc. still would not. This is a regression and a userspace ABI change. Problem originally reported here: http://thread.gmane.org/gmane.linux.kernel.autofs/6098 It appears that there was an attempt at fixing various userspace tools to not trigger the automount. But since the stat system call is rather common it is impossible to "fix" all userspace. This patch reverts the original behavior, which is to not trigger on stat(2) and other symlink following syscalls. [ It's not really clear what the right behavior is. Apparently Solaris does the "automount on stat, leave alone on lstat". And some programs can get unhappy when "stat+open+fstat" ends up giving a different result from the fstat than from the initial stat. But the change in 2.6.38 resulted in problems for some people, so we're going back to old behavior. Maybe we can re-visit this discussion at some future date - Linus ] Reported-by: Leonardo Chiquitto <leonardo.lists@gmail.com> Signed-off-by: Miklos Szeredi <mszeredi@suse.cz> Acked-by: Ian Kent <raven@themaw.net> Cc: David Howells <dhowells@redhat.com> Cc: stable@kernel.org Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> 09 September 2011, 22:42:34 UTC

This patch provides a function which reads the mac address stored in SPI flash (registered as MTD device) and populates the EMAC platform data. The function which reads the mac address is registered as a callback which gets called upon addition of MTD device. NOTE: In case the MAC address stored in SPI flash is erased, follow the instructions at [1] to restore it. [1] http://processors.wiki.ti.com/index.php/GSG:_OMAP-L138_DVEVM_Additional_Procedures#Restoring_MAC_address_on_SPI_Flash Modifications in v2: Guarded registering the mtd_notifier only when MTD is enabled. Earlier this was handled using mtd_has_partitions() call, but this has been removed in Linux v3.0. Modifications in v3: a. Guarded da850_evm_m25p80_notify_add() function and da850evm_spi_notifier structure with CONFIG_MTD macros. b. Renamed da850_evm_register_mtd_user() function to da850_evm_setup_mac_addr() and removed the struct mtd_notifier argument to this function. c. Passed the da850evm_spi_notifier structure to register_mtd_user() function. Modifications in v4: Moved the da850_evm_setup_mac_addr() function within the first CONFIG_MTD ifdef construct.

Then, in tegra_i2c_isr, we will call again tegra_i2c_fill_tx_fifo triggering weird behaviour. This has been shown to happen under real conditions.

d7cb666 Jonas Bonn 30 July 2011, 14:15:42 UTC openrisc: don't use pt_regs in struct sigcontext As it was decided not to export struct pt_regs to userspace, struct sigcontext shouldn't be using it either. The pt_regs struct for OpenRISC is kernel internal and the layout of the registers may change in the future. The struct user_regs_struct is what is guaranteed to remain stable, so struct sigcontext may use that instead. This patch removes the usage of struct pt_regs in struct sigcontext and makes according changes in signal.c to get the register layout right. The usp field is removed from the sigcontext structure as this information is already contained in the user_regs_struct.
