features/quota: Metadata cleanup
Quota and marker uses 'trusted.glusterfs.quota*' and 'trusted.pgfid*' xattrs to
store its configurations and accounting information and also to build the
parent inode chain in case of absense of path.
Problem:
After disabling and then enabling quota back, the xattrs may contain stale data
leading to impaired accounting and thus improper enforcement.
Solution:
Clean up all the quota related xattrs after quota disable.
Marker xlator implements a virtual xattr to cleanup quota and pgfid xattrs. In
this approach glusterd mounts an auxiliary mount and sends the below command to
all the files by crawling the mountpoint.
#setfattr -n "glusterfs.quota-xattr-cleanup" -v 1 <path/to/file>
