[GIT PULL] Ceph fixes for -rc2

[GIT PULL] Ceph fixes for -rc2

[Sage Weil]

Hi Linus,

Please pull the following Ceph fixes from

  git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client.git for-linus

We have a few follow-up fixes for the libceph refactor from Ilya, and then 
some cephfs + fscache fixes from Zheng.  The first two FS-Cache patches 
are acked by David Howells and deemed trivial enough to go through our 
tree.  The rest fix some issues with the ceph fscache handling (disable 
cache for inodes opened for write, and simplify the revalidation logic 
accordingly, dropping the now-unnecessary work queue).

Thanks!
sage

Ilya Dryomov (3):
      libceph: change ceph_osdmap_flag() to take osdc
      libceph: put request only if it's done in handle_reply()
      libceph: use %s instead of %pE in dout()s

Yan, Zheng (7):
      FS-Cache: wake write waiter after invalidating writes
      FS-Cache: make check_consistency callback return int
      ceph: call __fscache_uncache_page() if readpages fails
      ceph: avoid unnecessary fscache invalidation/revlidation
      ceph: disable fscache when inode is opened for write
      ceph: improve fscache revalidation
      ceph: use i_version to check validity of fscache

  libceph: advertise support for keepalive2 (2015-09-17 20:14:27 +0300)

These are both fixes to the new and improved keepalive2 behavior.

Thanks!

Hi Linus,

Please pull the following Ceph fixes from

  git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client.git for-linus

There is a fix for CephFS and RBD when used within containers/namespaces, 
and a fix for the address learning the client is supposed to do when 
initially talking to the Ceph cluster.

There are also two patches updating MAINTAINERS.  One breaks out the 
common Ceph code shared by fs/ceph and drivers/block/rbd.c into a separate 
entry with the appropriate maintainers listed.  The second adds a second 
reference to the github tree where the Ceph client development takes place 
(before it is pushed to korg and then to you).  The goal here is to move 
closer to a situation where Ilya Dryomov or one of the other maintainers 
can push things to you if I am unavailable.  Ilya has done most of the 
work preparing branches for upstream recently; you should not be surprised 
to hear from him if I am trapped in some internet-less wasteland or hit by 
a bus or something.  In the meantime, we'll work on getting him added to 
the kernel web of trust.

Thanks-
sage

There is an RBD fix for a crash due to the immutable bio changes, an error

Hi Linus,

Please pull the following patches from

  git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client.git for-linus

Yes, this is a much larger pull than I would like after -rc1.  There are a 
few things included:

 - a few fixes for leaks and incorrect assertions
 - a few patches fixing behavior when mapped images are resized
 - handling for cloned/layered images that are flattened out from 
   underneath the client

The last bit was non-trivial, and there is some code movement and 
associated cleanup mixed in.  This was ready and was meant to go in last 
week but I missed the boat on Friday.  My only excuse is that I was 
waiting for an all clear from the testing and there were many other shiny 
things to distract me.

Strictly speaking, handling the flatten case isn't a regression and could 
wait, so if you like we can try to pull the series apart, but Alex and I 
would much prefer to have it all in as it is a case real users will hit 
with 3.10.

Thanks!
sage
