Subject: [PATCH] Fix resolving devices with names that look like BIOS drive
number
A RAID array named "10" will not be resolved because we try to
resolve it using EDD data and after this lookup fails, we don't
try the name.
Resolves: rhbz#1960798

Subject: [PATCH] Do not set chunk size for RAID 1
Setting chunk size for RAID 1 doesn't make sense and latest
mdadm started returning error instead of ignoring the --chunk
option when creating an array.
