So that fsr can attempt to get the fork offset of the temporary inode it uses the same as the inode it is defragmenting, pass the fork offset out in the bulkstat information. The bulkstat structure has padding that has always been zeroed, so userspace can tell if this field is set or not by use of the xattr present flag and a non-zero value for the fork offset.

The current default size of the reserved blocks pool is easy to deplete with certain workloads, in particular workloads that do lots of concurrent delayed allocation extent conversions. If enough transactions are running in parallel and the entire pool is consumed then subsequent calls to xfs_trans_reserve() will fail with ENOSPC. Also add a rate limited warning so we know if this starts happening again. This is an updated version of an old patch from Lachlan McIlroy.

We currently use block_invalidatepage() to clean up pages where I/O fails in ->writepage(). Unfortunately, if the page has delalloc regions on it, we fail to remove the delalloc regions when we invalidate the page. This can result in tripping a BUG() in xfs_get_blocks() later on if a direct IO read is done on that same region - the delalloc extent is returned when none is supposed to be there. Fix this by truncating away the delalloc regions on the page before invalidating it. Because they are delalloc, we can do this without needing a transaction. Indeed - if we get ENOSPC errors, we have to be able to do this truncation without a transaction as there is no space left for block reservation (typically why we see a ENOSPC in writeback).

xfssyncd processes a queue of work by detaching the queue and then iterating over all the work items. It then sleeps for a time period or until new work comes in. If new work is queued while xfssyncd is actively processing the detached work queue, it will not process that new work until after a sleep timeout or the next work event queued wakes it. Fix this by checking the work queue again before going to sleep.

The radix-tree code requires it's users to serialize tag updates against other updates to the tree. While XFS protects tag updates against each other it does not serialize them against updates of the tree contents, which can lead to tag corruption. Fix the inode cache to always take pag_ici_lock in exclusive mode when updating radix tree tags.

The introduction of barriers to loop devices has created a new IO order completion dependency that XFS does not handle. The loop device implements barriers using fsync and so turns a log IO in the XFS filesystem on the loop device into a data IO in the backing filesystem. That is, the completion of log IOs in the loop filesystem are now dependent on completion of data IO in the backing filesystem. This can cause deadlocks when a flush daemon issues a log force with an inode locked because the IO completion of IO on the inode is blocked by the inode lock. This in turn prevents further data IO completion from occuring on all XFS filesystems on that CPU (due to the shared nature of the completion queues). This then prevents the log IO from completing because the log is waiting for data IO completion as well. The fix for this new completion order dependency issue is to make the IO completion inode locking non-blocking. If the inode lock can't be grabbed, simply requeue the IO completion back to the work queue so that it can be processed later. This prevents the completion queue from being blocked and allows data IO completion on other inodes to proceed, hence avoiding completion order dependent deadlocks.

While doing some testing of readdir perf a while back, I noticed that the buffer size we're using internally is smaller than what glibc gives us by default. Upping this size helped a bit, and seems safe. glibc's __alloc_dir() does: const size_t default_allocation = (4 * BUFSIZ < sizeof (struct dirent64) ? sizeof (struct dirent64) : 4 * BUFSIZ); const size_t small_allocation = (BUFSIZ < sizeof (struct dirent64) ? sizeof (struct dirent64) : BUFSIZ); size_t allocation = default_allocation; #ifdef _STATBUF_ST_BLKSIZE if (statp != NULL && default_allocation < statp->st_blksize) allocation = statp->st_blksize; #endif and #define _G_BUFSIZ 8192 #define _IO_BUFSIZ _G_BUFSIZ # define BUFSIZ _IO_BUFSIZ so the default buffer is 4 * 8192 = 32768 (except in the unlikely case of blocks > 32k....)

Traffic (tcp) doesnot start on a vlan interface when gro is enabled. Even the tcp handshake was not taking place. This is because, the eth_type_trans call before the netif_receive_skb in napi_gro_finish() resets the skb->dev to napi->dev from the previously set vlan netdev interface. This causes the ip_route_input to drop the incoming packet considering it as a packet coming from a martian source. I could repro this on 2.6.32.7 (stable) and 2.6.33-rc7. With this fix, the traffic starts and the test runs fine on both vlan and non-vlan interfaces.

The netif_wake_queue() is called correctly (i.e. only on !txfull condition) from txdone routine. So Unconditional call to the netif_wake_queue() here is wrong. This might cause calling of start_xmit routine on txfull state and trigger BUG_ON. This bug does not happen when NAPI disabled. After txdone there must be at least one free tx slot. But with NAPI, this is not true anymore and the BUG_ON can hits on heavy load. In this driver NAPI was enabled on 2.6.33-rc1 so this is regression from 2.6.32 kernel.
