Merge tag 'ceph-for-4.12-rc1' of git://github.com/ceph/ceph-client

Pull ceph updates from Ilya Dryomov:
 "The two main items are support for disabling automatic rbd exclusive
  lock transfers from myself and the long awaited -ENOSPC handling
  series from Jeff.

  The former will allow rbd users to take advantage of exclusive lock's
  built-in blacklist/break-lock functionality while staying in control
  of who owns the lock. With the latter in place, we will abort
  filesystem writes on -ENOSPC instead of having them block
  indefinitely.

  Beyond that we've got the usual pile of filesystem fixes from Zheng,
  some refcount_t conversion patches from Elena and a patch for an
  ancient open() flags handling bug from Alexander"

libceph, ceph: always advertise all supported features

2017-05-04T07:19:18+00:00

No reason to hide CephFS-specific features in the rbd case.  Recent
feature bits mix RADOS and CephFS-specific stuff together anyway.

ceph: Convert to separately allocated bdi

2017-04-20T18:09:55+00:00

Allocate struct backing_dev_info separately instead of embedding it
inside client structure. This unifies handling of bdi among users.

ceph: remove special ack vs commit behavior

2017-02-24T18:04:57+00:00

- ask for a commit reply instead of an ack reply in
  __ceph_pool_perm_get()
- don't ask for both ack and commit replies in ceph_sync_write()
- since just only one reply is requested now, i_unsafe_writes list
  will always be empty -- kill ceph_sync_write_wait() and go back to
  a standard ->evict_inode()

ceph: set io_pages bdi hint

2017-02-20T11:16:05+00:00

This patch sets the io_pages bdi hint based on the rsize mount option.
Without this patch large buffered reads (request size > max readahead)
are processed sequentially in chunks of the readahead size (i.e. read
requests are sent out up to the readahead size, then the
do_generic_file_read() function waits until the first page is received).

With this patch read requests are sent out at once up to the size
specified in the rsize mount option (default: 64 MB).

Merge tag 'ceph-for-4.10-rc1' of git://github.com/ceph/ceph-client

2016-12-16T19:23:34+00:00

Pull ceph updates from Ilya Dryomov:
 "A varied set of changes:

   - a large rework of cephx auth code to cope with CONFIG_VMAP_STACK
     (myself). Also fixed a deadlock caused by a bogus allocation on the
     writeback path and authorize reply verification.

   - a fix for long stalls during fsync (Jeff Layton). The client now
     has a way to force the MDS log flush, leading to ~100x speedups in
     some synthetic tests.

   - a new [no]require_active_mds mount option (Zheng Yan).

     On mount, we will now check whether any of the MDSes are available
     and bail rather than block if none are. This check can be avoided
     by specifying the "no" option.

   - a couple of MDS cap handling fixes and a few assorted patches
     throughout"
