Revision 553698f944ed715dfe023b4cef07601f0ce735f0 authored by Jens Axboe on 14 June 2006, 17:11:57 UTC, committed by Linus Torvalds on 14 June 2006, 17:22:16 UTC
We don't clear the seek stat values in cfq_alloc_io_context(), and if ->seek_mean is unlucky enough to be set to -36 by chance, the first invocation of cfq_update_io_seektime() will oops with a divide by zero in do_div(). Just memset the entire cic instead of filling invididual values independently. Signed-off-by: Jens Axboe <axboe@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
