Subject: [PATCH 0/2] md: fix fix deadlock while suspending RAID array

Hi,

This patch series fixes a deadlock which have been observed while
updating a RAID array level, using the mdadm --grow command. A full
description of the issue (hopefully understandable enough) is provided
by the commit message in the second patch.

Please, let me know if this patches are correct and/or if there is an
another way (maybe more handy) to solve this deadlock issue.

Thanks,

Simon
