#     treewide: uapi: Replace zero-length arrays with flexible-array members
#     
#     There is a regular need in the kernel to provide a way to declare
#     having a dynamically sized set of trailing elements in a structure.
#     Kernel code should always use “flexible array members”[1] for these
#     cases. The older style of one-element or zero-length arrays should
#     no longer be used[2].
#     
#     This code was transformed with the help of Coccinelle:
#     (linux-5.19-rc2$ spatch --jobs $(getconf _NPROCESSORS_ONLN) --sp-file script.cocci --include-headers --dir . > output.patch)
#     
#     @@
#     identifier S, member, array;
#     type T1, T2;
#     @@
#     
#     struct S {
#       ...
#       T1 member;
#       T2 array[
#     - 0
#       ];
#     };
#     
#     -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.
