get you, i_mutex is always hold during the map block process, it is i_data_sem that be used to protect extent block usage.

However, obdfilter takes i_mutex on writes and truncates and serializes extent map updates with it.</p> <p>Which case/race is expected to be handled with your code that I quoted above?</p> <p>Thanks.</p> <p>Panda, I think you are right, I also couldn't find where the extent tree got changed w/o i_mutex hold, but the in the 1st place, in walk_space, ext4_ext_find_extent is called with i_data_sem protection, then there should exist case where extent got change w/o i_mutex protection, so the issue should be what Bzzz mentioned, we'd protect extent access, i.e. put ldiskfs_ext_next_allocated_block() under i_data_sem lock hold.</p> Bugzilla ID 23780.0 Development Rank 1|hzv93r: Rank (Obsolete) 5009 Severity
