[PATCH 0/2] Add xfs test coverage for ro external dev mounts

[Hans Holmberg <Hans.Holmberg@wdc.com>]

These two patches adds test coverage for verifying that xfs file
systems with external log and rt devices marked as read only will be
mounted and remounted correctly. 

The first patch adds test coverage for xfs external rt devs.

ext4 already has a test for log devices that can be shared, so the
second patch turns that test generic.

This is an updated resend of these two patches:

https://lore.kernel.org/fstests/20250502113415.14882-1-hans.holmberg@wdc.com/

Updates:
 - Added _fixed_by_kernel_commit(s) as suggested by Ted
 - Made sure the the new xfs test is skipped on internal rt file systems
