Re: XFS Bug null pointer dereference in xfs_free_ag_extent

Test again......very strange.
I can easily reproduce it on the XFS with SAN(FLX380) connected with a qlogic 2400 FC card.

Everything is right when I using ext3/reiser4/reiserfs with FLX380,qlogic 2400.
Everything is right too when I using XFS with a normal scsi storage or a raid storage(NOT a SAN).

No, I got zero feedback, but let's cc the correct

Is this easily reproducible for you? I've not seen it before, and
the only possibly related recent changes I can think of are these:;a=commit;h=e63a3690013a475746ad2cea998ebb534d825704;a=commit;h=d210a28cd851082cec9b282443f8cc0e6fc09830

Could you try reverting each of those to see if either is the cause?
