From 6c031f41db15b6cb0cd33545cec28ca706cd3c7e Mon Sep 17 00:00:00 2001 From: Milan Broz Date: Fri, 10 Oct 2008 13:37:06 +0100 Subject: [PATCH] dm crypt: move dec_pending on error into write_io_submit Make kcryptd_crypt_write_io_submit() responsible for decrementing the pending count after an error. Also fixes a bug in the async path that forgot to decrement it.
