flexible-array transformations in UAPI for 6.0-rc1

Browse source 
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
