From ab8d0fc48dba09e0a2b8b0dbfe144d4de9eb874f Mon Sep 17 00:00:00 2001 From: Jeff Mahoney Date: Tue, 20 Sep 2016 10:05:02 -0400 Subject: btrfs: convert pr_* to btrfs_* where possible For many printks, we want to know which file system issued the message. This patch converts most pr_* calls to use the btrfs_* versions instead. In some cases, this means adding plumbing to allow call sites access to an fs_info pointer. fs/btrfs/check-integrity.c is left alone for another day.
