[dm-devel] [PATCH 2/2] dm flakey: document that default I/O error is only for write (resend)

[kusumi.tomohiro at gmail.com]

From: Tomohiro Kusumi <kusumi.tomohiro at gmail.com>

.map of dm-flakey with no optional feature parameters specified
results in -EIO only for writes during down time. Read bios are
submitted as usual whether it's in up or down time.
