GENERIC_PERMISSION(9)		 The Linux VFS		 GENERIC_PERMISSION(9)

NAME
       generic_permission - check for access rights on a Posix-like filesystem

SYNOPSIS
       int generic_permission(struct inode * inode, int mask,
			      int (*check_acl) (struct inode *inode, int mask));

ARGUMENTS
       inode
	   inode to check access rights for

       mask
	   right to check for (MAY_READ, MAY_WRITE, MAY_EXEC)

       check_acl
	   optional callback to check for Posix ACLs

DESCRIPTION
       Used to check for read/write/execute permissions on a file. We use
       “fsuid” for this, letting us set arbitrary permissions for filesystem
       access without changing the “normal” uids which are used for other
       things..
