[ANNOUNCE 2/2] xfs-linux: xfile-page-caching updated to 7645630a8125

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi folks,

The xfile-page-caching branch of the xfs-linux repository at:

git://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfs-linux.git

has just been updated for your review.

This code snapshot has been rebased against recent upstream, freshly
QA'd, and is ready for people to examine.  For veteran readers, the new
snapshot can be diffed against the previous snapshot; and for new
readers, this is a reasonable place to begin reading.  For the best
experience, it is recommended to pull this branch and walk the commits
instead of trying to read any patch deluge.

This is the 6.3-rc5 rebase of all the online repair code, all the way to
the end of part 1.  This contains fixes for the low-hanging fruit that
Dave mentioned on #xfs last week.

The new head of the xfile-page-caching branch is commit:

7645630a8125 xfile: implement write caching
