2006-11-11[XFS] Prevent a deadlock when xfslogd unpins inodes.David Chinner
The previous fixes for the use after free in xfs_iunpin left a nasty log deadlock when xfslogd unpinned the inode and dropped the last reference to the inode. the ->clear_inode() method can issue transactions, and if the log was full, the transaction could push on the log and get stuck trying to push the inode it was currently unpinning. To fix this, we provide xfs_iunpin a guarantee that it will always have a valid xfs_inode <-> linux inode link or a particular flag will be set on the inode. We then use log forces during lookup to ensure transactions are completed before we recycle the inode. This ensures that xfs_iunpin will never use the linux inode after it is being freed, and any lookup on an inode on the reclaim list will wait until it is safe to attach a new linux inode to the xfs inode.

2006-09-28[XFS] Really fix use after free in xfs_iunpin.David Chinner
The previous attempts to fix the linux inode use-after-free in xfs_iunpin simply made the problem harder to hit. We actually need complete exclusion between xfs_reclaim and xfs_iunpin, as well as ensuring that the i_flags are consistent during both of these functions. Introduce a new spinlock for exclusion and the i_flags, and fix up xfs_iunpin to use igrab before marking the inode dirty.

writes. In addition flush the disk cache on fsync if the sync cached operation didn't sync the log to disk (this requires some additional bookeping in the transaction and log code). If the device doesn't claim to support barriers, the filesystem has an extern log volume or the trial superblock write with barriers enabled failed we disable barriers and print a warning. We should probably fail the mount completely, but that could lead to nasty boot failures for the root filesystem. Not enabled by default yet, needs more destructive testing first.

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!
