Subject: bcachefs: -EROFS doesn't count as move_extent_start_fail
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=1b1bd0fd41577400434d5948edc2679092c57b08;p=linux.git

bcachefs: -EROFS doesn't count as move_extent_start_fail

The automated tests check if we've hit too many slowpath/error path
events and fail the test - if we're just shutting down, that naturally
shouldn't count.
