Filesystems must explicitly enable cleancache by calling cleancache_init_fs anytime an instance of the filesystem is mounted. For ext3, 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@...p.org: simplify init hook and any future fs init changes] Signed-off-by: Dan Magenheimer <dan.magenheimer@...cle.com> Reviewed-by: Jeremy Fitzhardinge <jeremy@...p.org> Reviewed-by: Konrad Rzeszutek Wilk <konrad.wilk@...cle.com> Acked-by: Andreas Dilger <adilger@....com> Cc: Ted Ts'o <tytso@....edu> Cc: Andrew Morton <akpm@...ux-foundation.org> Cc: Al Viro <viro@...IV.linux.org.uk> Cc: Matthew Wilcox <matthew@....cx> Cc: Nick Piggin <npiggin@...nel.dk> Cc: Mel Gorman <mel@....ul.ie> Cc: Rik Van Riel <riel@...hat.com> Cc: Jan Beulich <JBeulich@...ell.com> Cc: Chris Mason <chris.mason@...cle.com> Cc: Mark Fasheh <mfasheh@...e.com> Cc: Joel Becker <joel.becker@...cle.com> Cc: Nitin Gupta <ngupta@...are.org> --- Diffstat: fs/ext3/super.c | 2 ++ 1 file changed, 2 insertions(+) --- linux-2.6.39-rc3/fs/ext3/super.c 2011-04-11 18:21:51.000000000 -0600 +++ linux-2.6.39-rc3-cleancache/fs/ext3/super.c 2011-04-13 17:10:40.918915872 -0600 @@ -36,6 +36,7 @@ #include <linux/quotaops.h> #include <linux/seq_file.h> #include <linux/log2.h> +#include <linux/cleancache.h> #include <asm/uaccess.h> @@ -1367,6 +1368,7 @@ static int ext3_setup_super(struct super } else { ext3_msg(sb, KERN_INFO, "using internal journal"); } + cleancache_init_fs(sb); return res; } -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
