<td valign=top bgcolor="#99cccc"><font face="Helvetica, Arial">
Next round of xfs_repair(8) performance improvements
(xfsprogs 2.9.2 onwards). It substantially improves the
I/O performance compared to previous versions through
the use of batch reads, background metadata prefetching
and smart priority based libxfs caching. Lost+found
behaviour has also been changed and will not re-orphan
existing lost+found files.

<tr><td valign=top bgcolor="#88ee88"><font face="Helvetica, Arial">
July-2007
</font></td>
<td valign=top bgcolor="#99cccc"><font face="Helvetica, Arial">
Added new data allocator called "filestreams" to 2.6.22
kernels. It allows a directory to reserve an allocation
group for exclusive use by files created within that
directory. Files being written in other directories will
not use the same allocation group and so files within
different directories will not interleave extents on disk.
The reservation is only active while files are being
created and written into the directory. Filestreams can
be enabled filesystem wide with a "-o filestreams" mount
option, or on a per directory basis with an xfs_io(8)
chattr flag.

<tr><td valign=top bgcolor="#88ee88"><font face="Helvetica, Arial">
June-2007
</font></td>
<td valign=top bgcolor="#99cccc"><font face="Helvetica, Arial">
Added a new tool, xfs_metadump(8), to capture the metadata

to xfs_repair(8).

May-2007

counters in the superblock.

March-2007
</font></td>
<td valign=top bgcolor="#99cccc"><font face="Helvetica, Arial">
Fixed the notorious "NULL files" problem after
a crash. The fix improves the syncronisation between
updates of the file size and writes that extend a file.
