From 16f408dc6b1c87f5e3a767626df09c1399c6bf70 Mon Sep 17 00:00:00 2001 From: Sagi Grimberg Date: Wed, 13 Aug 2014 14:49:31 +0300 Subject: [PATCH] block: Fix BUG_ON when pi errors occur When getting a pi error we get to bio_integrity_end_io with bi_remaining already decremented to 0 where we will eventually need to call bio_endio with restored original bio completion handler. Calling bio_endio invokes a BUG_ON(). We should call bio_endio_nodec instead, like what is done in bio_integrity_verify_fn.
