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 --- fs/configfs/inode.c | 2 +- fs/hugetlbfs/inode.c | 2 +- fs/ocfs2/dlm/dlmfs.c | 2 +- fs/ramfs/inode.c | 2 +- fs/sysfs/inode.c | 2 +- 5 files changed, 5 insertions(+), 5 deletions(-) (limited to 'fs') diff --git a/fs/configfs/inode.c b/fs/configfs/inode.c index 4c1ebff778ee..b9a1d810346d 100644 --- a/fs/configfs/inode.c +++ b/fs/configfs/inode.c @@ -47,7 +47,7 @@ static const struct address_space_operations configfs_aops = { static struct backing_dev_info configfs_backing_dev_info = { .ra_pages = 0, /* No readahead */ - .capabilities = BDI_CAP_NO_ACCT_DIRTY | BDI_CAP_NO_WRITEBACK, + .capabilities = BDI_CAP_NO_ACCT_AND_WRITEBACK, }; static const struct inode_operations configfs_inode_operations ={ diff --git a/fs/hugetlbfs/inode.c b/fs/hugetlbfs/inode.c index 9783723e8ffe..aeabf80f81a5 100644 --- a/fs/hugetlbfs/inode.c +++ b/fs/hugetlbfs/inode.c @@ -45,7 +45,7 @@ static const struct inode_operations hugetlbfs_inode_operations; static struct backing_dev_info hugetlbfs_backing_dev_info = { .ra_pages = 0, /* No readahead */ - .capabilities = BDI_CAP_NO_ACCT_DIRTY | BDI_CAP_NO_WRITEBACK, + .capabilities = BDI_CAP_NO_ACCT_AND_WRITEBACK, }; int sysctl_hugetlb_shm_group; diff --git a/fs/ocfs2/dlm/dlmfs.c b/fs/ocfs2/dlm/dlmfs.c index 61a000f8524c..e48aba698b77 100644 --- a/fs/ocfs2/dlm/dlmfs.c +++ b/fs/ocfs2/dlm/dlmfs.c @@ -327,7 +327,7 @@ clear_fields: static struct backing_dev_info dlmfs_backing_dev_info = { .ra_pages = 0, /* No readahead */ - .capabilities = BDI_CAP_NO_ACCT_DIRTY | BDI_CAP_NO_WRITEBACK, + .capabilities = BDI_CAP_NO_ACCT_AND_WRITEBACK, }; static struct inode *dlmfs_get_root_inode(struct super_block *sb) diff --git a/fs/ramfs/inode.c b/fs/ramfs/inode.c index 8428d5b2711d..b13123424e49 100644 --- a/fs/ramfs/inode.c +++ b/fs/ramfs/inode.c @@ -44,7 +44,7 @@ static const struct inode_operations ramfs_dir_inode_operations; static struct backing_dev_info ramfs_backing_dev_info = { .ra_pages = 0, /* No readahead */ - .capabilities = BDI_CAP_NO_ACCT_DIRTY | BDI_CAP_NO_WRITEBACK | + .capabilities = BDI_CAP_NO_ACCT_AND_WRITEBACK | BDI_CAP_MAP_DIRECT | BDI_CAP_MAP_COPY | BDI_CAP_READ_MAP | BDI_CAP_WRITE_MAP | BDI_CAP_EXEC_MAP, }; diff --git a/fs/sysfs/inode.c b/fs/sysfs/inode.c index d9262f74f94e..f8b82e73b3bf 100644 --- a/fs/sysfs/inode.c +++ b/fs/sysfs/inode.c @@ -30,7 +30,7 @@ static const struct address_space_operations sysfs_aops = { static struct backing_dev_info sysfs_backing_dev_info = { .ra_pages = 0, /* No readahead */ - .capabilities = BDI_CAP_NO_ACCT_DIRTY | BDI_CAP_NO_WRITEBACK, + .capabilities = BDI_CAP_NO_ACCT_AND_WRITEBACK, }; static const struct inode_operations sysfs_inode_operations ={ -- cgit v1.2.3
