Hi Chris,
Please consider the following changes (or a subset at your will in case
they are too many or too large) for the kernel 4.2 release. All these
patches have been available in the mailing list for at least 2 weeks.
They are all bug fixes and deal with races, crashes, memory corruption,
hangs and data loss on fsync. No cleanups, refactorings or other cosmetic
changes that don't affect users, except for a change that updates a
comment added in a change that was already sent to Linus (but that can
hardly introduce any regression).
I have included 2 fixes from Liu related to error handling of direct IO
writes because not only they seem important to me, I also tested and
reviewed them. My recent patch for direct IO error handling (not included
in this pull request because it's too fresh) does not depend on Liu's
fixes, it's for a different error case (when we fail to submit the bios),
and can be tested/applied with or without his fixes.
Finally I have included a fix from Shilong that has been around since
April and didn't got any attention, despite being correct, trivial and
useful.
I have added Reviewed-By and Tested-by tags to all the patches that got
such tags from people through the mailing list. Some patches are also
tagged for stable.
I have rebased them on top of your current integration-4.2 branch and
re-tested them with xfstests, LTP and some custom tests. Some of these
fixes have new test cases for xfstest submitted recently as well (but
not yet merged as of today, only reviewed).
Thanks.
