Merge tag 'flexible-array-transformations-UAPI-6.0-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gustavoars/linux
Pull uapi flexible array update from Gustavo Silva:
"A treewide patch that replaces zero-length arrays with flexible-array
members in UAPI. This 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"
