916a307 Ben Dooks 01 October 2009, 22:44:15 UTC s3cmci: change GPIO to gpiolib from S3C24XX specific calls Move to using gpiolib to access the card detect and write protect GPIO lines instead of using the platform speicifc s3c2410_gpio calls. Also ensure that the card lines are claimed the same way to avoid overlap with any other drivers.

ef8745c KAMEZAWA Hiroyuki 01 October 2009, 22:44:12 UTC memcg: reduce check for softlimit excess In charge/uncharge/reclaim path, usage_in_excess is calculated repeatedly and it takes res_counter's spin_lock every time. This patch removes unnecessary calls for res_count_soft_limit_excess.

4e64915 KAMEZAWA Hiroyuki 01 October 2009, 22:44:11 UTC memcg: some modification to softlimit under hierarchical memory reclaim. This patch clean up/fixes for memcg's uncharge soft limit path. Problems: Now, res_counter_charge()/uncharge() handles softlimit information at charge/uncharge and softlimit-check is done when event counter per memcg goes over limit. Now, event counter per memcg is updated only when memory usage is over soft limit. Here, considering hierarchical memcg management, ancesotors should be taken care of. Now, ancerstors(hierarchy) are handled in charge() but not in uncharge(). This is not good. Prolems: 1. memcg's event counter incremented only when softlimit hits. That's bad. It makes event counter hard to be reused for other purpose. 2. At uncharge, only the lowest level rescounter is handled. This is bug. Because ancesotor's event counter is not incremented, children should take care of them. 3. res_counter_uncharge()'s 3rd argument is NULL in most case. ops under res_counter->lock should be small. No "if" sentense is better. Fixes: * Removed soft_limit_xx poitner and checks in charge and uncharge. Do-check-only-when-necessary scheme works enough well without them. * make event-counter of memcg incremented at every charge/uncharge. (per-cpu area will be accessed soon anyway) * All ancestors are checked at soft-limit-check. This is necessary because ancesotor's event counter may never be modified. Then, they should be checked at the same time.

Then, the caller of this function has to call css_put(mz->mem->css). But, mz can be !NULL even if "not found" i.e. without css_get(). By this, css->refcnt will go down to minus. This may cause various things...one of results will be initite-loop in css_tryget() as this.

6646679 Stephen Hemminger 01 October 2009, 07:11:46 UTC sky2: irqname based on pci address This is based on Michal Schmidt fix for skge. Most network drivers request their IRQ when the interface is activated. sky2 does it in ->probe() instead, because it can work with two-port cards where the two net_devices use the same IRQ. This works fine most of the time, except in some situations when the interface gets renamed. Consider this example: 1. modprobe sky2 The card is detected as eth0 and requests IRQ 17. Directory /proc/irq/17/eth0 is created. 2. There is an udev rule which says this interface should be called eth1, so udev renames eth0 -> eth1. 3. modprobe 8139too The Realtek card is detected as eth0. It will be using IRQ 17 too. 4. ip link set eth0 up Now 8139too requests IRQ 17. The result is: WARNING: at fs/proc/generic.c:590 proc_register ... proc_dir_entry '17/eth0' already registered The fix is for sky2 to name the irq based on the pci device, as is done by some other devices DRM, infiniband, ... ie. sky2@pci:0000:00:00 Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Reviewed-by: Michal Schmidt <mschmidt@redhat.com> Signed-off-by: David S.

And "ls /proc/irq/17" shows two subdirectories, both called eth0. Fix it by using a unique name for skge's IRQ, based on the PCI address. The naming from the example then looks like this: $ grep skge /proc/interrupts 17: 169 IO-APIC-fasteoi skge@pci:0000:00:0a.0, eth0 irqbalance daemon will have to be taught to recognize "skge@" as an Ethernet interrupt.

89e95a6 Ori Finkelman 01 October 2009, 06:41:59 UTC IPv4 TCP fails to send window scale option when window scale is zero Acknowledge TCP window scale support by inserting the proper option in SYN/ACK and SYN headers even if our window scale is zero. This fixes the following observed behavior: 1. Client sends a SYN with TCP window scaling option and non zero window scale value to a Linux box. 2. Linux box notes large receive window from client. 3. Linux decides on a zero value of window scale for its part. 4. Due to compare against requested window scale size option, Linux does not to send windows scale TCP option header on SYN/ACK at all. With the following result: Client box thinks TCP window scaling is not supported, since SYN/ACK had no TCP window scale option, while Linux thinks that TCP window scaling is supported (and scale might be non zero), since SYN had TCP window scale option and we have a mismatched idea between the client and server regarding window sizes. Probably it also fixes up the following bug (not observed in practice): 1. Linux box opens TCP connection to some server. 2. Linux decides on zero value of window scale. 3. Due to compare against computed window scale size option, Linux does not to set windows scale TCP option header on SYN. With the expected result that the server OS does not use window scale option due to not receiving such an option in the SYN headers, leading to suboptimal performance.

That means if you release the primary slave and enslave it again, it becomes the primary slave again. But if you set primary slave via sysfs, the primary slave is only set once and it's not remembered in bond->params structure. Therefore the setting is lost after releasing the primary slave.

The fix is to clear any delalloc bits for the range we are dirtying so the space accounting gets handled properly. This is the same thing we do in the normal write case, so we are consistent across the board. With this patch we no longer leak reserved space.

67efc92 Christoph Hellwig 30 September 2009, 11:54:20 UTC block: allow large discard requests Currently we set the bio size to the byte equivalent of the blocks to be trimmed when submitting the initial DISCARD ioctl. That means it is subject to the max_hw_sectors limitation of the HBA which is much lower than the size of a DISCARD request we can support. Add a separate max_discard_sectors tunable to limit the size for discard requests. We limit the max discard request size in bytes to 32bit as that is the limit for bio->bi_size. This could be much larger if we had a way to pass that information through the block layer.

c15227d Christoph Hellwig 30 September 2009, 11:52:12 UTC block: use normal I/O path for discard requests prepare_discard_fn() was being called in a place where memory allocation was effectively impossible. This makes it inappropriate for all but the most trivial translations of Linux's DISCARD operation to the block command set. Additionally adding a payload there makes the ownership of the bio backing unclear as it's now allocated by the device driver and not the submitter as usual. It is replaced with QUEUE_FLAG_DISCARD which is used to indicate whether the queue supports discard operations or not. blkdev_issue_discard now allocates a one-page, sector-length payload which is the right thing for the common ATA and SCSI implementations. The mtd implementation of prepare_discard_fn() is replaced with simply checking for the request being a discard. Largely based on a previous patch from Matthew Wilcox <matthew@wil.cx> which did the prepare_discard_fn but not the different payload allocation yet.

3bd0f0c Suresh Jayaraman 30 September 2009, 08:53:48 UTC swapfile: avoid NULL pointer dereference in swapon when s_bdev is NULL While testing Swap over NFS patchset, I noticed an oops that was triggered during swapon. Investigating further, the NULL pointer deference is due to the SSD device check/optimization in the swapon code that assumes s_bdev could never be NULL. inode->i_sb->s_bdev could be NULL in a few cases. For e.g. one such case is loopback NFS mount, there could be others as well. Fix this by ensuring s_bdev is not NULL before we try to deference s_bdev.

7bfc4ab Anton Vorontsov 01 October 2009, 03:11:11 UTC 3c59x: Rework suspend and resume As noticed by Alan Stern, there is still one issue with the driver: we disable PCI IRQ on suspend, but other devices on the same IRQ line might still need the IRQ enabled to suspend properly. Nowadays, PCI core handles all power management work by itself, with one condition though: if we use dev_pm_ops. So, rework the driver to only quiesce 3c59x internal logic on suspend, while PCI core will manage PCI device power state with IRQs disabled. Suggested-by: Rafael J.
