From 7aa5325e1b50b9f42745f522576e77e14df55686 Mon Sep 17 00:00:00 2001 From: Chen Zhongjin Date: Fri, 9 Dec 2022 18:04:48 +0800 Subject: [PATCH] fs: sysv: Fix sysv_nblocks() returns wrong value [ Upstream commit e0c49bd2b4d3cd1751491eb2d940bce968ac65e9 ] sysv_nblocks() returns 'blocks' rather than 'res', which only counting the number of triple-indirect blocks and causing sysv_getattr() gets a wrong result. [AV: this is actually a sysv counterpart of minixfs fix - 0fcd426de9d0 "[PATCH] minix block usage counting fix" in historical tree; mea culpa, should've thought to check fs/sysv back then...] Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2") Signed-off-by: Chen Zhongjin Signed-off-by: Al Viro Signed-off-by: Sasha Levin --- fs/sysv/itree.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/fs/sysv/itree.c b/fs/sysv/itree.c index bcb67b0cabe7..31f66053e239 100644 --- a/fs/sysv/itree.c +++ b/fs/sysv/itree.c @@ -438,7 +438,7 @@ static unsigned sysv_nblocks(struct super_block *s, loff_t size) res += blocks; direct = 1; } - return blocks; + return res; } int sysv_getattr(const struct path *path, struct kstat *stat,
