Description

Currently inherit attribute could be changed by FS_IOC_FSSETXATTR
and FS_IOC_SETFLAGS, we have permission check for FS_IOC_FSSETXATTR
,but FS_IOC_SETFLAGS could be done with regular users.

Regular users could use this to clear directory inherit attribute which could break directory quota.
