| Subject: btrfs: sysfs: fix format string for some discard stats |
| |
| From: David Sterba <dsterba@suse.com> |
| |
| [ Upstream commit 8c5ec995616f1202ab92e195fd75d6f60d86f85c ] |
| |
| The type of discard_bitmap_bytes and discard_extent_bytes is u64 so the |
| format should be %llu, though the actual values would hardly ever |
| overflow to negative values. |
