Subject: [PATCH 0/2] scsi: aacraid: struct sgmap: Replace 1-element arrays with flexible arrays

Hi,

This replaces some of the last remaining uses in the kernel of 1-element
"fake" flexible arrays with modern C99 flexible arrays. Some refactoring
is done to ease this, and binary differences are identified. For the
on stack size changes in patch 2, the "yes, that is the source of the binary
differences" debugging patch can be found here[1].

Thanks!

-Kees
