[PATCH AUTOSEL 5.12 69/80] btrfs: sysfs: fix format string for some discard stats
From: Sasha Levin
Date: Sun Jul 04 2021 - 19:10:09 EST
From: David Sterba <dsterba@xxxxxxxx>
[ 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.
