[PATCH 6.6 071/134] io_uring: enable io_mem_alloc/free to be used in other parts

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jens Axboe <axboe@xxxxxxxxx>

commit edecf1689768452ba1a64b7aaf3a47a817da651a upstream.

In preparation for using these helpers, make them non-static and add
them to our internal header.
