linux.git/fs/ceph/inode.c, branch v3.17

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"

ceph: remember subtree root dirfrag's auth MDS

2014-06-06T01:29:55+00:00

remember dirfrag's auth MDS when it's different from its parent inode's
auth MDS.

ceph: introduce ceph_fill_fragtree()

2014-06-06T01:29:54+00:00

Move the code that update the i_fragtree into a separate function.
Also add simple probabilistic test to decide whether the i_fragtree
should be updated

ceph: pre-allocate ceph_cap struct for ceph_add_cap()

2014-06-06T01:29:53+00:00

So that ceph_add_cap() can be used while i_ceph_lock is locked.
This simplifies the code that handle cap import/export.

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.

ceph: clear directory's completeness when creating file

2014-04-28T19:54:44+00:00

When creating a file, ceph_set_dentry_offset() puts the new dentry
at the end of directory's d_subdirs, then set the dentry's offset
based on directory's max offset. The offset does not reflect the
real postion of the dentry in directory. Later readdir reply from
MDS may change the dentry's position/offset. This inconsistency
can cause missing/duplicate entries in readdir result if readdir
is partly satisfied by dcache_readdir().

The fix is clear directory's completeness after creating/renaming
file. It prevents later readdir from using dcache_readdir().
