[PATCH 0/3] Enable xfs error reporting to print out error codes

[cem@kernel.org]

From: Carlos Maiolino <cem@kernel.org>

Hello.

This is the first 'formal' version of this series after a round of
RFC...

The goal remains the same, enabling us to easily find what error
caused a transaction to be cancelled. But the infra-structure is usable
for remaining error cases.

The main updates regarding the RFC version is xfs_error_report now
uses errname() to print out the error.

Also gets rid of the unneeded extern modifier from it.

Instead of a variadic function uses a couple different macros to select
between with/without error. I named it xfs_trans_cancel_error() because
it sounded clear to me than the _with() suffix. I'd not join an argument
to defent one or another though if you guys are unhappy with _error,
I'll change back to _with().

Last patch is simple enough and I kept Darrick's review on it as there
is not much change in there other than setting up the right macro.

Cheers.

Carlos Maiolino (3):
  xfs: add xfs_error_report the ability to display an error code
  xfs: enable xfs_trans_cancel() to report and error code
  xfs: make xfs_iomap_write_direct() report an error to xfs_trans_cancel
