Subject: scripts/atomic/check-atomics.sh: don't assume that scripts are executable
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=df38354323f52324bb014168d9f3825c0e78a56a;p=users%2Fwilly%2Flinux.git

scripts/atomic/check-atomics.sh: don't assume that scripts are executable

patch(1) doesn't set the x bit on files.  So if someone downloads and
applies patch-4.21.xz, their kernel won't build.  Fix that by executing
/bin/sh.
