From ba28b93a5227cc69ec811507f7d85ac25fa20fe2 Mon Sep 17 00:00:00 2001 From: Akshat Aranya Date: Fri, 14 Jan 2011 16:00:47 +0000 Subject: FS-Cache: Fix operation handling fscache_submit_exclusive_op() adds an operation to the pending list if other operations are pending. Fix the check for pending ops as n_ops must be greater than 0 at the point it is checked as it is incremented immediately before under lock.
