Change f to unsigned int to resolve the mismatch in format specifiers for snprintf(), where %u should be used for unsigned integers instead of %d Signed-off-by: Zhu Jun <zhujun2@xxxxxxxxxxxxxxxxxxxx> --- Changes: v2: A better fix is to make f "unsigned int" as that is consistent with g_nr_zones and the fact that up to "unsigned int" total number of zones are allowed for a zoned device. Can you send a v2 ? Also please add a Fixes tag. fs/zonefs/super.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/fs/zonefs/super.c b/fs/zonefs/super.c index faf1eb878..695da258a 100644 --- a/fs/zonefs/super.c +++ b/fs/zonefs/super.c @@ -791,7 +791,7 @@ static int zonefs_readdir_zgroup(struct file *file, int fname_len; char *fname; ino_t ino; - int f; + unsigned int f; /* * The size of zone group directories is equal to the number -- 2.17.1
