[PATCH V2 0/3] Print when ENOSPC due to lack of inodes in non-inode64 mount.

[raghu.prabhu13 at gmail.com]

From: Raghavendra D Prabhu <rprabhu at wnohang.net>

Currently, when there are no free inodes left / free space to allocate them (usually
without inode64), there is no indication anywhere of this case, making it harder
to diagnose this case. 

Hence, this series prints the causes/reasons to kernel log in a ratelimited
manner, when such a situation arises.

----- 
Version 1: Initially sent with pr_err_once to print the error only once.

Version 2: Added ratelimited functions to xfs_message.h instead of printing once
with pr_err_once on suggestion of Dave Chinner.

Raghavendra D Prabhu (3):
  Add ratelimited printk for different alert levels
  XFS: Print error when xfs_ialloc_ag_select fails to find continuous
    free space.
  XFS: Print error when unable to allocate inodes or out of free
    inodes.
