VRTSvxfs
vxfs_ap_assign_fs()
assigns the given allocation policies for data and metadata
to a file system.
The
fd
argument can reference any file within the file system.
To clear a policy assignment,
specify a NULL pointer for the policy field to be cleared (either
datapol
or
metapol).
To use this function,
specify
-l vxfsutil
while linking.
Assigning or defining an allocation policy can fail because of a
conflict with volume flags.
The conflict detection attempts to detect all conflicts,
but there is no guarantee that all conflicts will be detected.
This API supports file
system versions 6.0 and above.
vxfs_ap_assign_fs()
returns zero on success,
non-zero on failure.
