Introduce a new mount option "nologreplay" to co-operate with "ro" mount

Maybe name it "norecovery" too, for simplicity and consistency?
That's also our first idea.
But the sad fact is, btrfs already has a mount option called "recovery".
So "norecovery" here will just be considered as a mount option to
disable "recovery", and that will make things more confusing.
And finally we choose the name "nologreplay".
Thanks,

The actual effect of "norecovery" in ext* and xfs is to also disable log
replay, but that's an under-the-hood detail not relevant to the user.

Mount options for ext3
norecovery/noload
Don't load the journal on mounting. Note that if the filesystem
was not unmounted cleanly, skipping the journal replay will lead
to the filesystem containing inconsistencies that can lead to
any number of problems.

Mount options for xfs
norecovery
The filesystem will be mounted without running log recovery. If
the filesystem was not cleanly unmounted, it is likely to be
inconsistent when mounted in norecovery mode. Some files or
directories may not be accessible because of this. Filesystems
mounted norecovery must be mounted read-only or the mount will
fail.
