[PATCH] xattr: infrastructure for permission overrides
Patch from Andreas Gruenbacher <agruen@suse.de>
This adds flags parameters to the getxattr, listxattr, and removexattr inode
operations. This is in preparation for the next patch, which allows
in-kernel code (i.e., modules) to override extended attribute permission
restrictions (which in turn is used by HSM implementations and the like).
