From 40bd62eb7fb8447798732e809a676ebaf2a7f910 Mon Sep 17 00:00:00 2001 From: Goldwyn Rodrigues <rgoldwyn@gmail.com> Date: Wed, 3 Jul 2013 15:00:53 -0700 Subject: [PATCH] fs/ocfs2/journal.h: add bits_wanted while calculating credits in ocfs2_calc_extend_credits While adding extends to a file, the credits are calculated incorrectly and if the requested clusters is more than one (or more because we used a conservative limit) then we run out of journal credits and we hit an assert in journalling code. The function parameter bits_wanted variable was not used at all.
