Subject: block: move timeout field in struct request to pack better
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1dd5198b2df913aec9b77c14529f9ff1b6d33e30;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

block: move timeout field in struct request to pack better

After commit 64c7f1d1572c, we went from 1 to 2 holes in my
test setup. If we move the timeout field a bit, we remove
both of those holes and shrink struct request by 8 bytes.
