s3:vfs_gpfs: Report disk space and usage on GPFS share according to quotas
When a client requests the information about free space and space used,
adjust the reported values according to quotas in the GPFS file system:
- Retrieve quotas for the current user, current group and fileset for
the top level of the share.
- If the soft block quota grace time has expired, report disk as full.
- If a hard block quota has been exceeded, report disk as full.
- If none of the hard block quotas been exceeded, report
share size and free space according to the lowest limits found in
the quotas.
- If no applicable hard block quota has been set, report the
information from the statfs call.
This feature is disabled by default and has to be enabled by setting the
option gpfs:dfreequota.
