[PATCH 37/38] btrfs: Make get_extent_t take btrfs_inode
From: Nikolay Borisov <hidden>
Date: 2017-02-17 14:44:24
Subsystem:
btrfs file system, filesystems (vfs and infrastructure), the rest · Maintainers:
Chris Mason, David Sterba, Alexander Viro, Christian Brauner, Linus Torvalds
In addition to changing the signature, this patch also switches all the functions which are used as an argument to also take btrfs_inode. Namely those are: btrfs_get_extent and btrfs_get_extent_filemap.
