[PATCH v2 0/1] nvme: Add fault injection feature

[Thomas Tai]

Linux's fault injection framework provides a systematic way to support
error injection via debugfs in the /sys/kernel/debug directory. This
patch uses the framework to add error injection to NVMe driver. 

Change log since last version:
V1:
1. move error injection point into nvme_end_request()
2. Add expected result in the commit log

Thank you,
Thomas
