Hi, folks,
These 3 patches add ACL support for UBIFS.
UBIFS ACL is based on xattr, which simplifies the implementation without
considering budget and sync.
New kernel/mount options, CONFIG_UBIFS_FS_POSIX_ACL and `-o acl', are
introduced to enable or disable UBIFS ACL.
`acl.c' provides format conversion between in-memory ACL and on-flash ACL.
Each time a new inode is created, the correspondng ACL xattr is built
(except for the inode of an xattr dent).
Testcases (adjusted to mount an UBI volume) in LTP [1] are passed.
Any comment is appreciated.
V2:
* Do not set ACL-xattr-handler, and call generic ACL handler in xattr
functions.
V1:

thanks,
