  treewide: uapi: Replace zero-length arrays with flexible-array members (2022-06-28 21:26:05 +0200)

----------------------------------------------------------------
flexible-array transformations in UAPI for 6.0-rc1

Hi Linus,

Please, pull the following treewide patch that replaces zero-length arrays
with flexible-array members in UAPI. This patch has been baking in
linux-next for 5 weeks now.

-fstrict-flex-arrays=3 is coming and we need to land these changes
to prevent issues like these in the short future:

../fs/minix/dir.c:337:3: warning: 'strcpy' will always overflow; destination buffer has size 0,
but the source string has length 2 (including NUL byte) [-Wfortify-source]
		strcpy(de3->name, ".");
		^

Since these are all [0] to [] changes, the risk to UAPI is nearly zero. If
this breaks anything, we can use a union with a new member name.

Thanks

Gustavo
