2010-12-20xfs: Pull EFI/EFD handling out from under the AIL lockDave Chinner
EFI/EFD interactions are protected from races by the AIL lock. They are the only type of log items that require the the AIL lock to serialise internal state, so they need to be separated from the AIL lock before we can do bulk insert operations on the AIL. To acheive this, convert the counter of the number of extents in the EFI to an atomic so it can be safely manipulated by EFD processing without locks. Also, convert the EFI state flag manipulations to use atomic bit operations so no locks are needed to record state changes. Finally, use the state bits to determine when it is safe to free the EFI and clean up the code to do this neatly.

2010-12-20xfs: fix EFI transaction cancellation.Dave Chinner
XFS_EFI_CANCELED has not been set in the code base since xfs_efi_cancel() was removed back in 2006 by commit 065d312e15902976d256ddaf396a7950ec0350a8 ("[XFS] Remove unused iop_abort log item operation), and even then xfs_efi_cancel() was never called. I haven't tracked it back further than that (beyond git history), but it indicates that the handling of EFIs in cancelled transactions has been broken for a long time. Basically, when we get an IOP_UNPIN(lip, 1); call from xfs_trans_uncommit() (i.e. remove == 1), if we don't free the log item descriptor we leak it. Fix the behviour to be correct and kill the XFS_EFI_CANCELED flag. Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: Christoph Hellwig <hch@lst.de>
2009-01-22[XFS] remove always-true #ifndef HAVE_FORMAT32 testsEric Sandeen
There are several tests for #ifndef HAVE_FORMAT32, but this is never defined anywhere so it is always the default behavior; just remove the ifndef goop.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
