Subject: io_uring/memmap: drop unused sz param in io_uring_validate_mmap_request()
X-Git-Tag: v6.19-rc4~9^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=70eafc743016b1df73e00fd726ffedd44ce1bdd3;p=thirdparty%2Flinux.git

io_uring/memmap: drop unused sz param in io_uring_validate_mmap_request()

io_uring_validate_mmap_request() doesn't use its size_t sz argument, so
remove it.
