[PATCH] repair: fix the call to search_rt_dup_extent in scan_bmapbt

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



search_rt_dup_extent expects an RT extent number and not a fsbno.
Convert the units before the call.  Without this we are unlikely
to ever found a legit duplicate extent on the RT subvolume because
the search will always be off the end.
