[PATCH 17/17] btrfs: unexport btrfs_get_io_geometry()
From: Qu Wenruo <hidden>
Date: 2021-12-01 05:18:43
Also in:
dm-devel, linux-btrfs
Subsystem:
btrfs file system, filesystems (vfs and infrastructure), the rest · Maintainers:
Chris Mason, David Sterba, Alexander Viro, Christian Brauner, Linus Torvalds
This function provides a lighter weight version of btrfs_map_block(), just to provide enough info without filling everything of btrfs_map_block(). But that function is only used for stripe boundary calculation, and now stripe boundary calculation is all handled inside btrfs_map_bio(), there is no need to export it anymore.
