Subject: io_uring: move to separate directory
X-Git-Tag: v6.0-rc1~181^2~170
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=ed29b0b4fd835b058ddd151c49d021e28d631ee6;p=thirdparty%2Fkernel%2Flinux.git

io_uring: move to separate directory

In preparation for splitting io_uring up a bit, move it into its own
top level directory. It didn't really belong in fs/ anyway, as it's
not a file system only API.

This adds io_uring/ and moves the core files in there, and updates the
MAINTAINERS file for the new location.
