From 6b81e14e645016597c81e71cd27ee5c57c3a3c36 Mon Sep 17 00:00:00 2001 From: Jiro SEKIBA Date: Thu, 14 Oct 2010 13:52:00 +0900 Subject: [PATCH] nilfs2: eliminate sparse warning - "context imbalance" insert sparse annotations to fix following sparse warning. fs/nilfs2/segment.c:2681:3: warning: context imbalance in 'nilfs_segctor_kill_thread' - unexpected unlock nilfs_segctor_kill_thread is only called inside sc_state_lock lock. sparse doesn't detect the context and warn "unexpected unlock". __acquires/__releases pretend to lock/unlock the sc_state_lock for sparse.
