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

2017-05-10T15:42:33+00:00

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"

ceph: allow connecting to mds whose rank >= mdsmap::m_max_mds

2017-05-04T07:19:20+00:00

mdsmap::m_max_mds is the expected count of active mds. It's not the
max rank of active mds. User can decrease mdsmap::m_max_mds, but does
not stop mds whose rank >= mdsmap::m_max_mds.

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: convert bools in ceph_mds_request to a new r_req_flags field

2017-02-20T11:16:08+00:00

Currently, we have a bunch of bool flags in struct ceph_mds_request. We
need more flags though, but each bool takes (at least) a byte. Those
add up over time.

Merge all of the existing bools in this struct into a single unsigned
long, and use the set/test/clear_bit macros to manipulate them. These
are atomic operations, but that is required here to prevent
load/modify/store races. The existing flags are protected by different
locks, so we can't rely on them for that purpose.

ceph: don't show symlink target in debugfs/mdsc

2016-05-25T23:15:32+00:00

symlink target is useless for debug and can be very long. It's annoying
to show it in debugfs/mdsc.
