The field: s_rd_only in the super_block structure appears to be unused except where it is set to zero in read_super() at super.c:535 and do_mount_root() at super.c:949. [Line numbers are taken from RedHat 2.0.32-3 kernel source].
It looks like the real way to tell if a file system is mounted read only is to test super_block.s_flags & MS_READONLY.
I'm working on a file system so would like to know (a) if this is correct and (b) if I need to worry about s_rd_only or if it will be deleted from the source tree `one of these days'.
Thanks in adv, Mike Howard <mike@clove.com>
