| d7ce584 | Miao Xie | 02 February 2010, 08:46:44 UTC | Btrfs: remove BUG_ON() due to mounting bad filesystem Mounting a bad filesystem caused a BUG_ON(). The following is steps to reproduce it. # mkfs.btrfs /dev/sda2 # mount /dev/sda2 /mnt # mkfs.btrfs /dev/sda1 /dev/sda2 (the program says that /dev/sda2 was mounted, and then exits. ) # umount /mnt # mount /dev/sda1 /mnt At the third step, mkfs.btrfs exited in the way of make filesystem. So the initialization of the filesystem didn't finish. So the filesystem was bad, and it caused BUG_ON() when mounting it. But BUG_ON() should be called by the wrong code, not user's operation, so I think it is a bug of btrfs. This patch fixes it.

The reason is the sanity check only looks at the total number of rw devices, which is just 2 because we have 2 good disks and 1 bad one. Instead check the total number of devices in the array to make sure we can actually remove the device.

So instead if we are in degraded mode, return 0 so we can go ahead and allocate stuff.

This can save considerable CPU because all future writes to the file go through uncompressed. But some files are both very large and have mixed data stored in them. In that case, we want to add the ability to always try compressing data before writing it. This commit adds mount -o compress-force. A later commit will add a new inode flag that does the same thing.

The reason for this is because we do not hold a reference on the block group while its caching, since the allocator drops its reference once it exits or moves on to the next block group.

This results in panic's like these http://www.kerneloops.org/oops.php?number=1109085 where adding an orphan entry results in -EEXIST being returned and we panic. In order to fix this, we check to see on lookup if our root has had the orphan cleanup done, and if not go ahead and do it. This is easily reproduceable by running this testcase #include <sys/types.h> #include <sys/stat.h> #include <fcntl.h> #include <string.h> #include <unistd.h> #include <stdio.h> int main(int argc, char **argv) { char data[4096]; char newdata[4096]; int fd1, fd2; memset(data, 'a', 4096); memset(newdata, 'b', 4096); while (1) { int i; fd1 = creat("file1", 0666); if (fd1 < 0) break; for (i = 0; i < 512; i++) write(fd1, data, 4096); fsync(fd1); close(fd1); fd2 = creat("file2", 0666); if (fd2 < 0) break; ftruncate(fd2, 4096 * 512); for (i = 0; i < 512; i++) write(fd2, newdata, 4096); close(fd2); i = rename("file2", "file1"); unlink("file1"); } return 0; } and then pulling the power on the box, and then trying to run that test again when the box comes back up.

| 35dead4 | Helge Deller | 02 December 2009, 23:29:15 UTC | modules: don't export section names of empty sections via sysfs On the parisc architecture we face for each and every loaded kernel module this kernel "badness warning": sysfs: cannot create duplicate filename '/module/ac97_bus/sections/.text' Badness at fs/sysfs/dir.c:487 Reason for that is, that on parisc all kernel modules do have multiple .text sections due to the usage of the -ffunction-sections compiler flag which is needed to reach all jump targets on this platform. An objdump on such a kernel module gives: Sections: Idx Name Size VMA LMA File off Algn 0 .note.gnu.build-id 00000024 00000000 00000000 00000034 2**2 CONTENTS, ALLOC, LOAD, READONLY, DATA 1 .text 00000000 00000000 00000000 00000058 2**0 CONTENTS, ALLOC, LOAD, READONLY, CODE 2 .text.ac97_bus_match 0000001c 00000000 00000000 00000058 2**2 CONTENTS, ALLOC, LOAD, READONLY, CODE 3 .text 00000000 00000000 00000000 000000d4 2**0 CONTENTS, ALLOC, LOAD, READONLY, CODE ... Since the .text sections are empty (size of 0 bytes) and won't be loaded by the kernel module loader anyway, I don't see a reason why such sections need to be listed under /sys/module/<module_name>/sections/<section_name> either. The attached patch does solve this issue by not exporting section names which are empty.

| 48a7f77 | Johannes Weiner | 01 December 2009, 21:17:48 UTC | rtc-x1205: fix rtc_time to y2k register value conversion The possible CCR_Y2K register values are 19 or 20 and struct rtc_time's tm_year is in years since 1900. The function translating rtc_time to register values assumes tm_year to be years since first christmas, though, and we end up storing 0 or 1 in the CCR_Y2K register, which the hardware does not refuse to do. A subsequent probing of the clock fails due to the invalid value range in the register, though. [ And if it didn't, reading the clock would yield a bogus year because the function translating registers to tm_year is assuming a register value of 19 or 20. ] This fixes the conversion from years since 1900 in tm_year to the corresponding CCR_Y2K value of 19 or 20.

| 315fe62 | Wu Zhangjin | 01 December 2009, 06:55:25 UTC | MIPS: Loongson: Disallow 4kB pages Currently, with PAGE_SIZE_4KB, the kernel for loongson will hang on: Kernel panic - not syncing: Attempted to kill init! The possible reason is the cache aliases problem: Loongson 2F has 64kb, 4 way L1 Cache, the way size is 16kb, which is bigger then 4kb. so, If using 4kb page size, there is cache aliases problem. To avoid this kind of problem, extra cache flushing. The 2nd possible solution is 16kb page size which avoids cache aliases without the need for extra cache flushes. So we disable 4kB pages until the aliasing issue is solved.

| d0e2607 | NeilBrown | 01 December 2009, 06:30:59 UTC | md: revert incorrect fix for read error handling in raid1. commit 4706b349f was a forward port of a fix that was needed for SLES10. But in fact it is not needed in mainline because the earlier commit dd00a99e7a fixes the same problem in a better way. Further, this commit introduces a bug in the way it interacts with the automatic read-error-correction. If, after a read error is successfully corrected, the same disk is chosen to re-read - the re-read won't be attempted but an error will be returned instead. After reverting that commit, there is the possibility that a read error on a read-only array (where read errors cannot be corrected as that requires a write) will repeatedly read the same device and continue to get an error. So in the "Array is readonly" case, fail the drive immediately on a read error. Signed-off-by: NeilBrown <neilb@suse.de> Cc: stable@kernel.org | 01 December 2009, 06:30:59 UTC |

It is then reset immediately by clearing the bit. When the interrupt handler is run, it does not detect an interrupt in the TCPPIMSKSR or RCPPIMSKSR registers and thus exits early without writing the TCPPIEOIR register. It appears that this inhibits further cppi interrupts until the handler is called by chance, f.ex. from davinci_interrupt(). By moving the unmasking of the interrupt below the writes to TCPPICOMPPTR, no interrupt is generated and no write to TCPPIEOIR is necessary.

Moreover, the driver starts Rx request despite of the endpoint being halted -- fix this by moving the SendStall bit check from musb_g_rx() to rxstate(). And we also sometimes get into rxstate() with DMA still active after clearing an endpoint's halt (not clear why), so bail out in this case, similarly to what txstate() does... While at it, also do the following changes : - in musb_gadget_set_halt(), remove pointless Tx FIFO flushing (the driver does not allow stalling with non-empty Tx FIFO anyway); - in rxstate(), stop pointlessly zeroing the 'csr' variable; - in musb_gadget_set_halt(), move the 'done' label to a more proper place; - in musb_g_rx(), eliminate the 'done' label completely...

| c2f6595 | Alan Stern | 18 November 2009, 16:37:15 UTC | USB: EHCI: don't send Clear-TT-Buffer following a STALL This patch (as1304) fixes a regression in ehci-hcd. Evidently some hubs don't handle Clear-TT-Buffer requests correctly, so we should avoid sending them when they don't appear to be absolutely necessary. The reported symptom is that output on a downstream audio device cuts out because the hub stops relaying isochronous packets. The patch prevents Clear-TT-Buffer requests from being sent following a STALL handshake. In theory a STALL indicates either that the downstream device sent a STALL or that no matching TT buffer could be found. In either case, the transfer is completed and the TT buffer does not remain busy, so it doesn't need to be cleared. Also, the patch fixes a minor flaw in the code that actually sends the Clear-TT-Buffer requests. Although the pipe direction isn't really used for control transfers, it should be a Send rather than a Receive.
