From: Linus Torvalds Date: Mon, 4 May 2020 16:16:37 +0000 (-0700) Subject: gcc-10 warnings: fix low-hanging fruit X-Git-Tag: v4.9.224~32 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5ba9126d709e5e7921413b7177ce3ecc98185670;p=thirdparty%2Fkernel%2Fstable.git gcc-10 warnings: fix low-hanging fruit commit 9d82973e032e246ff5663c9805fbb5407ae932e3 upstream. Due to a bug-report that was compiler-dependent, I updated one of my machines to gcc-10. That shows a lot of new warnings. Happily they seem to be mostly the valid kind, but it's going to cause a round of churn for getting rid of them.. This is the really low-hanging fruit of removing a couple of zero-sized arrays in some core code. We have had a round of these patches before, and we'll have many more coming, and there is nothing special about these except that they were particularly trivial, and triggered more warnings than most.
