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.
