Git-commit: 306bfec02b1054d24bbbeec49ece6db396d451e0
Patch-mainline: 5.10-rc1
References: bsc#1179217
Subject: [PATCH] btrfs: rename btrfs_punch_hole_range() to a more generic name
The function btrfs_punch_hole_range() is now used to replace all the file
extents in a given file range with an extent described in the given struct
btrfs_replace_extent_info argument. This extent can either be an existing
extent that is being cloned or it can be a new extent (namely a prealloc
extent). When that argument is NULL it only punches a hole (drops all the
existing extents) in the file range.
So rename the function to btrfs_replace_file_extents().
