Subject: btrfs: pass the extent map tree's inode to clear_em_logging()
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=002f3a2ce8b07d03aa46ed977ca86cdb30f3d668;p=users%2Fjedix%2Flinux-maple.git

btrfs: pass the extent map tree's inode to clear_em_logging()

Extent maps are always associated to an inode's extent map tree, so
there's no need to pass the extent map tree explicitly to
clear_em_logging().

In order to facilitate an upcoming change that adds a shrinker for extent
maps, change clear_em_logging() to receive the inode instead of its extent
map tree.
