2007-07-14[XFS] Only use refcounted pages for I/OChristoph Hellwig
Many block drivers (aoe, iscsi) really want refcountable pages in bios, which is what almost everyone send down. XFS unfortunately has a few places where it sends down buffers that may come from kmalloc, which breaks them. Fix the places that use kmalloc()d buffers.

2007-02-10[XFS] Current usage of buftarg flags is incorrect.David Chinner
The {test,set,clear}_bit() operations take a bit index for the bit to operate on. The XBT_* flags are defined as bit fields which is incorrect, not to mention the way the bit fields are enumerated is broken too. This was only working by chance. Fix the definitions of the flags and make the code using them use the {test,set,clear}_bit() operations correctly.

2005-11-02[XFS] write barrier support Issue all log sync operations as orderedChristoph Hellwig
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.

2005-09-05[XFS] Fix racy access to pb_flags. pagebuf_rele() modified pb_flags afterDavid Chinner
the pagebuf had been unlocked if the buffer was delwri. At high load, this could result in a race when the superblock was being synced that would result the flags being incorrect and the iodone functions being executed incorrectly. This then leads to iclog callback failures or AIL list corruptions resulting in filesystem shutdowns.

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!
