Subject: [PATCH] f2fs: fix to update age extent correctly during truncation
References: bsc#1012628
Patch-mainline: 6.2.5
Git-commit: 8c0ed062ce27f6b7f0a568cb241e2b4dd2d9e6a6
[ Upstream commit 8c0ed062ce27f6b7f0a568cb241e2b4dd2d9e6a6 ]
nr_free may be less than len, we should update age extent cache
w/ range [fofs, len] rather than [fofs, nr_free].
Fixes: 71644dff4811 ("f2fs: add block_age-based extent cache")
