Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs

2015-07-05T02:36:06+00:00

Pull more vfs updates from Al Viro:
 "Assorted VFS fixes and related cleanups (IMO the most interesting in
  that part are f_path-related things and Eric's descriptor-related
  stuff).  UFS regression fixes (it got broken last cycle).  9P fixes.
  fs-cache series, DAX patches, Jan's file_remove_suid() work"

[ I'd say this is much more than "fixes and related cleanups".  The
  file_table locking rule change by Eric Dumazet is a rather big and
  fundamental update even if the patch isn't huge.   - Linus ]

MAINTAINERS: BCACHE: Kent Overstreet has changed email address

2015-07-01T02:45:01+00:00

Kent's email address in MAINTAINERS seems to be invalid.
This was his last sign-off address, so use that if appropriate.

Fix the S: status entry while there.

Pull device mapper fixes from Mike Snitzer:
 "Apologies for not pressing this request-based DM partial completion
  issue further, it was an oversight on my part.  We'll have to get it
  fixed up properly and revisit for a future release.

   - Revert block and DM core changes the removed request-based DM's
     ability to handle partial request completions -- otherwise with the
     current SCSI LLDs these changes could lead to silent data
     corruption.

   - Fix two DM version bumps that were missing from the initial 4.2 DM
     pull request (enabled userspace lvm2 to know certain changes have
     been made)"

dm cache policy smq: fix "default" version to be 1.4.0

2015-06-26T14:14:28+00:00

Commit bccab6a0 ("dm cache: switch the "default" cache replacement
policy from mq to smq") should've incremented the "default" policy's
version number to 1.4.0 rather than reverting to version 1.0.0.

Revert "block, dm: don't copy bios for request clones"

2015-06-26T14:11:58+00:00

This reverts commit 5f1b670d0bef508a5554d92525f5f6d00d640b38.

Justification for revert as reported in this dm-devel post:
https://www.redhat.com/archives/dm-devel/2015-June/msg00160.html

this change should not be pushed to mainline yet.

Firstly, Christoph has a newer version of the patch that fixes silent
data corruption problem:
  https://www.redhat.com/archives/dm-devel/2015-May/msg00229.html

And the new version still depends on LLDDs to always complete requests
to the end when error happens, while block API doesn't enforce such a
requirement. If the assumption is ever broken, the inconsistency between
request and bio (e.g. rq->__sector and rq->bio) will cause silent data
corruption:

drivers/md/md.c: use strreplace()

2015-06-26T00:00:40+00:00

There's no point in starting over when we meet a '/'.  This also
eliminates a stack variable and a little .text.
