ceph: clear directory's completeness when creating file
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(). Fixes: http://tracker.ceph.com/issues/8025 Signed-off-by: Yan, Zheng <zheng.z.yan@intel.com> Reviewed-by: Sage Weil <sage@inktank.com>
