From e4ad08fe64afca4ef79ecc4c624e6e871688da0d Mon Sep 17 00:00:00 2001 From: Miklos Szeredi Date: Wed, 30 Apr 2008 00:54:37 -0700 Subject: mm: bdi: add separate writeback accounting capability Add a new BDI capability flag: BDI_CAP_NO_ACCT_WB. If this flag is set, then don't update the per-bdi writeback stats from test_set_page_writeback() and test_clear_page_writeback(). Misc cleanups: - convert bdi_cap_writeback_dirty() and friends to static inline functions - create a flag that includes all three dirty/writeback related flags, since almst all users will want to have them toghether Signed-off-by: Miklos Szeredi Cc: Peter Zijlstra Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- kernel/cgroup.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'kernel') diff --git a/kernel/cgroup.c b/kernel/cgroup.c index b9d467d83fc1..fbc6fc8949b4 100644 --- a/kernel/cgroup.c +++ b/kernel/cgroup.c @@ -575,7 +575,7 @@ static struct inode_operations cgroup_dir_inode_operations; static struct file_operations proc_cgroupstats_operations; static struct backing_dev_info cgroup_backing_dev_info = { - .capabilities = BDI_CAP_NO_ACCT_DIRTY | BDI_CAP_NO_WRITEBACK, + .capabilities = BDI_CAP_NO_ACCT_AND_WRITEBACK, }; static struct inode *cgroup_new_inode(mode_t mode, struct super_block *sb) -- cgit v1.2.3
