[PATCH v2 0/2] Move BTRFS RCU string to common library

[Omar Sandoval]

This patch series moves the generic RCU string library used internally by BTRFS
to be accessible by anyone. It provides printk_in_rcu and
printk_ratelimited_in_rcu to print these strings. In order to avoid a weird
inconsistency between the two, the first patch fixes printk_ratelimited so it
passes on the return value from printk.

The second patch actually moves the RCU string library. Version 2 passes on the
return values from printk{,_ratelimited} and fixes some style issues.

Omar Sandoval (2):
  Return a value from printk_ratelimited
