ceph: fix divide-by-zero in __validate_layout()

2014-10-14T19:57:05Z

The 'stripe_unit' field is 64 bits, casting it to 32 bits can result zero. Signed-off-by: Yan, Zheng

ceph: request xattrs if xattr_version is zero

2014-10-14T17:03:38Z

Following sequence of events can happen. - Client releases an inode, queues cap release message. - A 'lookup' reply brings the same inode back, but the reply doesn't contain xattrs because MDS didn't receive the cap release message and thought client already has up-to-data xattrs. The fix is force sending a getattr request to MDS if xattrs_version is 0. The getattr mask is set to CEPH_STAT_CAP_XATTR, so MDS knows client does not have xattr. Signed-off-by: Yan, Zheng

ceph: fix pr_fmt() redefinition

ceph: do not chain inode updates to parent fsync

2014-04-03T02:33:52Z

The fsync(dirfd) only covers namespace operations, not inode updates. We do not need to cover setattr variants or O_TRUNC. Reported-by: Al Viro Signed-off-by: Sage Weil Reviewed-by: Yan, Zheng

libceph: replace ceph_calc_ceph_pg() with ceph_oloc_oid_to_pg()

libceph: rename ceph_calc_object_layout()

2013-05-02T04:16:17Z

The purpose of ceph_calc_object_layout() is to fill in the pool number and seed for a ceph_pg structure provided, based on a given osd map and target object id. Currently that function takes a file layout parameter, but the only thing used out of that is its pool number. Change the function so it takes a pool number rather than the full file layout structure. Only update the ceph_pg if the pool is found in the osd map. Get rid of few useless lines of code from the function while there. Since the function now very clearly just fills in the ceph_pg structure it's provided, rename it ceph_calc_ceph_pg().
