From 7abc52c2ed169c65044d3a199879c8438ad82322 Mon Sep 17 00:00:00 2001 From: Dan Magenheimer Date: Thu, 26 May 2011 10:02:03 -0600 Subject: ext4: add cleancache support This seventh patch of eight in this cleancache series "opts-in" cleancache for ext4. Filesystems must explicitly enable cleancache by calling cleancache_init_fs anytime an instance of the filesystem is mounted. For ext4, all other cleancache hooks are in the VFS layer including the matching cleancache_flush_fs hook which must be called on unmount. Details and a FAQ can be found in Documentation/vm/cleancache.txt [v6-v8: no changes] [v5: jeremy@goop.org: simplify init hook and any future fs init changes] Signed-off-by: Dan Magenheimer Reviewed-by: Jeremy Fitzhardinge Reviewed-by: Konrad Rzeszutek Wilk Acked-by: Andreas Dilger Cc: Ted Ts'o Cc: Andrew Morton Cc: Al Viro Cc: Matthew Wilcox Cc: Nick Piggin Cc: Mel Gorman Cc: Rik Van Riel Cc: Jan Beulich Cc: Chris Mason Cc: Mark Fasheh Cc: Joel Becker Cc: Nitin Gupta --- fs/ext4/super.c | 2 ++ 1 file changed, 2 insertions(+) (limited to 'fs/ext4/super.c') diff --git a/fs/ext4/super.c b/fs/ext4/super.c index 8553dfb310af..51476477c818 100644 --- a/fs/ext4/super.c +++ b/fs/ext4/super.c @@ -38,6 +38,7 @@ #include #include #include +#include #include #include @@ -1932,6 +1933,7 @@ static int ext4_setup_super(struct super_block *sb, struct ext4_super_block *es, EXT4_INODES_PER_GROUP(sb), sbi->s_mount_opt, sbi->s_mount_opt2); + cleancache_init_fs(sb); return res; } -- cgit v1.2.3
