[PATCH 0/7] Configurable error behavior [V4]

[Carlos Maiolino]

New revision ot the patchset according with comments for V3.

This patchset is aimed to implement a configurable error behavior in XFS, and,
most of the design has been done by Dave, so, I kept his signed-off.

Detailed changelog is written on each patch, but, major changes are:

	- make fail_at_unmount a global configuration option inside
	  ../xfs/<dev>/err/fail_at_unmount

Carlos Maiolino (7):
  xfs: configurable error behavior via sysfs
  xfs: introduce metadata IO error class
  xfs: add configurable error support to metadata buffers
  xfs: introduce table-based init for error behaviors
  xfs: add configuration of error failure speed
  xfs: add configuration handlers for specific errors
  xfs: add "fail at unmount" error handling configuration
