Subject: io_uring/rsrc: bump struct io_mapped_ubuf length field to size_t
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ca76b56a2a2acf9875e5cad68612085f25b463bb;p=thirdparty%2Fkernel%2Flinux.git

io_uring/rsrc: bump struct io_mapped_ubuf length field to size_t

In preparation for supporting bigger individual buffers, bump the length
field to a full 8-bytes with size_t rather than an unsigned int.
