OK, I don't see a problem in this patch. But is there some benefit in it? I'm slightly nervous it could change something subtle...

The variable 'needs_recovery' in ext3_fill_super() only be used in this 'if' switch, but all the 'if' does is printing out a log message and no matter what value 'needs_recovery' is, ext3_mark_recovery_complete() is always being called. This change makes the logic more clear and of course reduce a little overhead when mounting clean fs. This change also consists with ext4 counter part 3733 if (needs_recovery) { 3734 ext4_msg(sb, KERN_INFO, "recovery complete"); 3735 ext4_mark_recovery_complete(sb, es); 3736 } But, yes, current code exists for a long time and no one complains about it, the change is trivial. If people worry more, I'm fine with skipping this patch. Thanks.

I'll take the patch. Thanks.

Call ext3_mark_recovery_complete() in ext3_fill_super() only if needs_recovery is non-zero. Besides that, print out "recovery complete" message after calling ext3_mark_recovery_complete().
