The current code always apply all flags from /etc/fstab on remount.
Unfortunately remount+bind has special semantic and it's impossible
from command line to avoid interaction with the "bind" from fstab.
Example, fstab:
/dev/sda1 /bar ext4 defaults 0 1
/bar /foo none bind 0 0
Command line:
# mount /foo -o remount,rw
produces:
mount(... MS_REMOUNT|MS_BIND ) syscall
This changes the per-mountpoint (VFS) ro flag to rw, but doesn't
change the filesystem itself.
This patch forces libmount to ignore "bind" from fstab when "-o
remount" specified on command line. If you need remount+bind semantic
you have to specify the "bind" flag on command line. This allow to
differentiate between
# mount /foo -o remount,bind,rw --> mount(MS_REMOUNT|MS_BIND)
and
# mount /foo -o remount,rw --> mount(MS_REMOUNT)
