2012-07-13xfs: prevent recursion in xfs_buf_iorequestChristoph Hellwig
If the b_iodone handler is run in calling context in xfs_buf_iorequest we can run into a recursion where xfs_buf_iodone_callbacks keeps calling back into xfs_buf_iorequest because an I/O error happened, which keeps calling back into xfs_buf_iorequest. This chain will usually not take long because the filesystem gets shut down because of log I/O errors, but even over a short time it can cause stack overflows if run on the same context. As a short term workaround make sure we always call the iodone handler in workqueue context.

2012-07-13xfs: don't defer metadata allocation to the workqueueDave Chinner
Almost all metadata allocations come from shallow stack usage situations. Avoid the overhead of switching the allocation to a workqueue as we are not in danger of running out of stack when making these allocations. Metadata allocations are already marked through the args that are passed down, so this is trivial to do.

2012-07-13block: fix infinite loop in __getblk_slowJeff Moyer
Commit 080399aaaf35 ("block: don't mark buffers beyond end of disk as mapped") exposed a bug in __getblk_slow that causes mount to hang as it loops infinitely waiting for a buffer that lies beyond the end of the disk to become uptodate. The problem was initially reported by Torsten Hilbrich here: https://lkml.org/lkml/2012/6/18/54 and also reported independently here: http://www.sysresccd.org/forums/viewtopic.php?f=13&t=4511 and then Richard W.M. Jones and Marcos Mello noted a few separate bugzillas also associated with the same issue. This patch has been confirmed to fix: https://bugzilla.redhat.com/show_bug.cgi?id=835019 The main problem is here, in __getblk_slow: for (;;) { struct buffer_head * bh; int ret; bh = __find_get_block(bdev, block, size); if (bh) return bh; ret = grow_buffers(bdev, block, size); if (ret < 0) return NULL; if (ret == 0) free_more_memory(); } __find_get_block does not find the block, since it will not be marked as mapped, and so grow_buffers is called to fill in the buffers for the associated page. I believe the for (;;) loop is there primarily to retry in the case of memory pressure keeping grow_buffers from succeeding. However, we also continue to loop for other cases, like the block lying beond the end of the disk. So, the fix I came up with is to only loop when grow_buffers fails due to memory allocation issues (return value of 0). The attached patch was tested by myself, Torsten, and Rich, and was found to resolve the problem in call cases.

2012-07-13cfg80211: reduce monitor interface trackingJohannes Berg
Revert commit b78e8ceac23655e1e06b30aa95ab11742d1ac7c0 ("cfg80211: track monitor channel") and remove the set_monitor_enabled() callback. Due to the tracking happening in NETDEV_PRE_UP, it had introduced bugs because the monitor interface callback would be called before the device was started. It looks like there's no way to fix this, and using NETDEV_PRE_UP is broken anyway (since there's no NETDEV_UP_FAIL), so remove all that code, track interfaces in NETDEV_UP and also stop tracking the monitor channel in cfg80211. This mostly reverts to before the tracking, except that we keep the interface count tracking so that setting the monitor channel can be rejected properly.

2012-07-13net: Update alloc frag to reduce get/put page usage and recycle pagesAlexander Duyck
This patch is meant to help improve performance by reducing the number of locked operations required to allocate a frag on x86 and other platforms. This is accomplished by using atomic_set operations on the page count instead of calling get_page and put_page. It is based on work originally provided by Eric Dumazet. In addition it also helps to reduce memory overhead when using TCP. This is done by recycling the page if the only holder of the frame is the netdev_alloc_frag call itself. This can occur when skb heads are stolen by either GRO or TCP and the driver providing the packets is using paged frags to store all of the data for the packets.
