Upon checking for what had changed for mdadm 2.4 prior to merging it, I found
2.4.1 is already out, with an update that affects RAID-5 superblock v1
resizing. There are cautions not to use 2.4 for that purpose, so it's probably
wise to replace 2.4 in the tree with 2.4.1, thus severity-normal, rather than
the usual enhancement, for a bump. (I'd consider higher severity, only 2.4 is
just out so few will have updated, and fewer still will use the affected
functionality.)
A simple rename/redigest of the 2.4 ebuild to 2.4.1 was all that was required.
