[v3,03/15] btrfs: move the printk helpers out of ctree.h

Series btrfs: split out larger chunks of ctree.h | expand

Commit Message

Josef Bacik Oct. 19, 2022, 2:50 p.m. UTC 
We have a bunch of printk helpers that are in ctree.h.  These have
nothing to do with ctree.c, so move them into their own header.
Subsequent patches will cleanup the printk helpers.
