Subject: [PATCH 0/5] ubi: Enhanced fault injection capability for the UBI driver

The existing fault injection capability of UBI is too simple.
It uses hard-coded fault probability values and lacks other
configurable options. As a result, these interfaces are difficult
to use when digging defects in the abnormal path of code and
reproducing some problems.

The kernel provides a powerful fault injection framework, which
provides rich configurable fault injection attributes during runtime.
So it can be used to improve the fault injection capability of the 
UBI driver.

This series of patches refactor the existing fault injection interface
and add some fault injection types to help testers and developers
find potential problems in the code.

ZhaoLong Wang (5):
  ubi: Using the Fault Injection Framework to refactor the debugfs
    interface
  ubi: Split io_failures into write_failure and erase_failure
  ubi: Add six fault injection type for testing
  ubi: Reserve sufficient buffer length for the input mask
  mtd: Add several functions to the fail_function list
