passes down hints with its policy.
alloc_mode=%s Adjust block allocation policy, which supports "reuse"
and "default".
fsync_mode=%s Control the policy of fsync. Currently supports "posix"
and "strict". In "posix" mode, which is default, fsync
will follow POSIX semantics and does a light operation
to improve the filesystem performance. In "strict" mode,
fsync will be heavy and behaves in line with xfs, ext4
and btrfs, where xfstest generic/342 will pass, but the
performance will regress.
fsync_mode=%s Control the policy of fsync. Currently supports "posix",
"strict", and "nobarrier". In "posix" mode, which is
default, fsync will follow POSIX semantics and does a
light operation to improve the filesystem performance.
In "strict" mode, fsync will be heavy and behaves in line
with xfs, ext4 and btrfs, where xfstest generic/342 will
pass, but the performance will regress. "nobarrier" is
based on "posix", but doesn't issue flush command for
non-atomic files likewise "nobarrier" mount option.
test_dummy_encryption Enable dummy encryption, which provides a fake fscrypt
context. The fake fscrypt context is used by xfstests.

@ -168,6 +168,15 @@ A: No. See above answer. In short, if you think it really belongs in
dash marker line as described in Documentation/SubmittingPatches to
temporarily embed that information into the patch that you send.
Q: Are all networking bug fixes backported to all stable releases?
A: Due to capacity, Dave could only take care of the backports for the last
2 stable releases. For earlier stable releases, each stable branch maintainer
is supposed to take care of them. If you find any patch is missing from an
earlier stable branch, please notify stable@vger.kernel.org with either a
commit ID or a formal patch backported, and CC Dave and other relevant
networking developers.
Q: Someone said that the comment style and coding convention is different
for the networking content. Is this true?
