Later OSD replies (for readahead) can't be handled. ceph_check_caps() also may lock snap_rwsem for read. So similar deadlock can happen if iput_final() is called while holding snap_rwsem. In general, it's not good to call iput_final() inside MDS/OSD dispatch threads or while holding any mutex. The fix is introducing ceph_async_iput(), which calls iput_final() in workqueue.

To support snapshot nfs re-export, we need a way to lookup snapped inode by file handle. For directory inode, snapped metadata are always stored together with head inode. Client just need to pass vinodeno_t to MDS. For non-directory inode, there can be multiple version of snapped inodes and they can be stored in different dirfrags. Besides vinodeno_t, client also need to tell mds from which dirfrag it got the snapped inode. Another problem of supporting snapshot nfs re-export is that there can be multiple paths to access a snapped inode. For example: mkdir -p d1/d2/d3 mkdir d1/.snap/s1 Paths 'd1/.snap/s1/d2/d3', 'd1/d2/.snap/_s1_<inode number of d1>/d3' and 'd1/d2/d3/.snap/_s1_<inode number of d1>' are all reference to the same snapped inode. For a given snapped inode, There is no convenient way to get the first form and the second form paths. For simplicity, ceph_get_parent() return snapdir for snapped directory inode. Furthermore, client may access snapshot of deleted directory. For example: mkdir -p d1/d2 mkdir d1/.snap/s1 open d1/.snap/s1/d2 rm -rf d1/d2 <nfs server restart> The path constucted by ceph_get_parent() and ceph_get_name() is '<inode of d2>/.snap/_s1_<inode number of d1>'. Futher lookup parent of <inode of d2> will fail. To workaround this case, this patch uses d_obtain_root() to get dentry for snapdir of deleted directory. snapdir dentry has no DCACHE_DISCONNECTED flag set, reconnect_path() stops when it reaches snapdir dentry.

The CephFS kernel client does not enforce quotas set in a directory that isn't visible from the mount point. For example, given the path '/dir1/dir2', if quotas are set in 'dir1' and the filesystem is mounted with mount -t ceph <server>:<port>:/dir1/ /mnt then the client won't be able to access 'dir1' inode, even if 'dir2' belongs to a quota realm that points to it. This patch fixes this issue by simply doing an MDS LOOKUPINO operation for unknown inodes. Any inode reference obtained this way will be added to a list in ceph_mds_client, and will only be released when the filesystem is umounted.

Dentry lease is added to tail of a list when it's updated, leases at front of the list will expire first. Dir lease is CEPH_CAP_FILE_SHARED on directory inode, it applies to all dentries in the directory. Dentries have dir leases are added to another list.
