Subject: MD: no sync IO while suspended
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=68866e425be2ef2664aa5c691bb3ab789736acf5;p=deliverable%2Flinux.git

MD: no sync IO while suspended

Disallow resync I/O while the RAID array is suspended.

Recovery, resync, and metadata I/O should not be allowed while a device is
suspended.
