commit 76e589013fec672c3587d6314f2d1f0aeddc26d9 upstream.
In the next patch, we're going to prohibit log recovery if the primary superblock contains an unrecognized rocompat feature bit even on readonly mounts. This requires removing all the code in the log mounting process that temporarily disables the readonly state.
Unfortunately, inode inactivation disables itself on readonly mounts. Clearing the iunlinked lists after log recovery needs inactivation to run to free the unreferenced inodes, which (AFAICT) is the only reason why log mounting plays games with the readonly state in the first place.
Therefore, change the inactivation predicates to allow inactivation during log recovery of a readonly mount.
