libceph: introduce ceph_osdc_cancel_request()

2014-07-08T11:08:44+00:00

Introduce ceph_osdc_cancel_request() intended for canceling requests
from the higher layers (rbd and cephfs).  Because higher layers are in
charge and are supposed to know what and when they are canceling, the
request is not completed, only unref'ed and removed from the libceph
data structures.

__cancel_request() is no longer called before __unregister_request(),
because __unregister_request() unconditionally revokes r_request and
there is no point in trying to do it twice.

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client

2014-06-13T06:06:23+00:00

Pull Ceph updates from Sage Weil:
 "This has a mix of bug fixes and cleanups.

  Alex's patch fixes a rare race in RBD.  Ilya's patches fix an ENOENT
  check when a second rbd image is mapped and a couple memory leaks.
  Zheng fixes several issues with fragmented directories and multiple
  MDSs.  Josh fixes a spin/sleep issue, and Josh and Guangliang's
  patches fix setting and unsetting RBD images read-only.

  Naturally there are several other cleanups mixed in for good measure"

libceph: add ceph_monc_wait_osdmap()

2014-06-06T01:29:57+00:00

Add ceph_monc_wait_osdmap(), which will block until the osdmap with the
specified epoch is received or timeout occurs.

Export both of these as they are going to be needed by rbd.

libceph: mon_get_version request infrastructure

2014-06-06T01:29:57+00:00

Add support for mon_get_version requests to libceph.  This reuses much
of the ceph_mon_generic_request infrastructure, with one exception.
Older OSDs don't set mon_get_version reply hdr->tid even if the
original request had a non-zero tid, which makes it impossible to
lookup ceph_mon_generic_request contexts by tid in get_generic_reply()
for such replies.  As a workaround, we allocate a reply message on the
reply path.  This can probably interfere with revoke, but I don't see
a better way.

ceph: update inode fields according to issued caps

2014-06-06T01:29:52+00:00

Cap message and request reply from non-auth MDS may carry stale
information (corresponding locks are in LOCK states) even they
have the newest inode version. So client should update inode fields
according to issued caps.
