* [XFS] kill INDUCE_IO_ERRORChristoph Hellwig2008-08-13
| | | | | | | | | | | | | | All the error injection is already enabled through ifdef DEBUG, so kill the never set second cpp symbol to activate it without the rest of the debugging infrastructure.

* [XFS] implement IHOLD/IRELE directlyChristoph Hellwig2008-08-13
| | | | | | | | | | | | | | | | | Now that all direct calls to VN_HOLD/VN_RELE are gone we can implement IHOLD/IRELE directly. For the IHOLD case also replace igrab with a direct increment of i_count because we are guaranteed to already have a live and referenced inode by the VFS. Also remove the vn_hold statistic because it's been rather meaningless for some time with most references done by other callers.

* [XFS] Use KM_NOFS for incore inode extent tree allocation V2David Chinner2008-08-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we allow incore extent tree allocations to recurse into the filesystem under memory pressure, new delayed allocations through xfs_iomap_write_delay() can deadlock on themselves if memory reclaim tries to write back dirty pages from that inode. It will deadlock in xfs_iomap_write_allocate() trying to take the ilock we already hold. This can also show up as complex ABBA deadlocks when multiple threads are triggering memory reclaim when trying to allocate extents. The main cause of this is the fact that delayed allocation is not done in a transaction, so KM_NOFS is not automatically added to the allocations to prevent this recursion. Mark all allocations done for the incore inode extent tree as KM_NOFS to ensure they never recurse back into the filesystem. Version 2: o KM_NOFS implies KM_SLEEP, so just use KM_NOFS SGI-PV: 981498 SGI-Modid: xfs-linux-melb:xfs-kern:31726a Signed-off-by: David Chinner <david@fromorbit.com> Signed-off-by: Niv Sardi <xaiki@sgi.com> Signed-off-by: Christoph Hellwig <hch@infradead.org> Signed-off-by: Lachlan McIlroy <lachlan@sgi.com>

* [XFS] Avoid directly referencing the VFS inode.David Chinner2008-08-13
| | | | | | | | | | | | | | | | | | | | In several places we directly convert from the XFS inode to the linux (VFS) inode by a simple deference of ip->i_vnode. We should not do this - a helper function should be used to extract the VFS inode from the XFS inode. Introduce the function VFS_I() to extract the VFS inode from the XFS inode. The name was chosen to match XFS_I() which is used to extract the XFS inode from the VFS inode.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a server supports unix extensions but does not support POSIX create routines, then the client will create a new inode with a standard SMB mkdir or create/open call and then will set the mode. When it does this, it does not take the setgid bit on the parent directory into account. This patch has CIFS flip on the setgid bit when the parent directory has it. If the share is mounted with "setuids" then also change the group owner to the gid of the parent. This patch should apply cleanly on top of the setattr cleanup patches that I sent a few weeks ago.

| * | ext4: Cleanup the block reservation code pathAneesh Kumar K.V2008-07-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The truncate patch should not use the i_allocated_meta_blocks value. So add seperate functions to be used in the truncate and alloc path. We also need to release the meta-data block that we reserved for the blocks that we are truncating.

| | | | | | | | | | | | | | | | | | | | | | | | With the FLEX_BG layout, there is no reason why extents can't cross block groups, so make the truncate code reserve enough credits so we don't BUG if we come across such an extent. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
