From 8c68a70170b31f93c287f29fd06c6c17edaf19ad Mon Sep 17 00:00:00 2001 From: Harald Hoyer Date: Wed, 17 Apr 2013 18:03:39 +0200 Subject: fixed statfs.f_type signed vs unsigned comparisons statfs.f_type is signed but the filesystem magics are unsigned. Casting the magics to signed will not make the signed. Problem seen on big-endian 64bit s390x with __fsword_t 8 bytes. Casting statfs.f_type to unsigned on the other hand will get us what we need. https://bugzilla.redhat.com/show_bug.cgi?id=953217 --- src/readahead/readahead-collect.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/readahead') diff --git a/src/readahead/readahead-collect.c b/src/readahead/readahead-collect.c index 03583928a0..6d7db4fae5 100644 --- a/src/readahead/readahead-collect.c +++ b/src/readahead/readahead-collect.c @@ -505,7 +505,7 @@ done: on_ssd = fs_on_ssd(root) > 0; log_debug("On SSD: %s", yes_no(on_ssd)); - on_btrfs = statfs(root, &sfs) >= 0 && (long) sfs.f_type == (long) BTRFS_SUPER_MAGIC; + on_btrfs = statfs(root, &sfs) >= 0 && (unsigned) sfs.f_type == BTRFS_SUPER_MAGIC; log_debug("On btrfs: %s", yes_no(on_btrfs)); if (asprintf(&pack_fn_new, "%s/.readahead.new", root) < 0) { -- cgit v1.2.3-54-g00ecf
