| H A D | quota.c | 0c44a8e0 Thu Mar 21 05:20:10 CDT 2019 Luis Henriques <lhenriques@suse.com> ceph: quota: fix quota subdir mounts
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.
