from inode list scans by default (unless there is an important reason to

Normally they will get excluded (eg.  by zero refcount or writecount etc),

Unroll essentials of do_remount_sb() into devpts

directly create/dirty files in /dev/pts so the MS_RDONLY flag and
shrinking the dcache does not really apply to devpts.

So effectively on remount, devpts only parses the mount options and updates
these options in its super block. As such, we could replace do_remount_sb()
call with a direct parse_mount_options().
