Abhishek Mishra 08afc5f2cf fs: enforce path search and unify inode permission helpers 
Require X_OK on path ancestors and mountpoint gates via
inode_checkpathperm(), and use inode_checkperm() for inode mode checks.
inode_checkpathperm() takes the inode tree read lock (or INODE_CHECK_LOCKED
when the caller already holds it) and can fold a non-zero amode check onto
the target inode in the same call.

When CONFIG_FS_PERMISSION is disabled, inode_checkperm/inode_checkpathperm
are empty macros returning 0 so there is no stub .text cost.

Skip mountpoint R/W open-mode checks in inode_checkopenperm(); keep
traversal separate from open.  Add an optional mountpt_operations.permission
hook (tmpfs when CONFIG_FS_PERMISSION) for in-volume DAC without making the
VFS mount-crossing path depend on it.
