Subject: [PATCH] io_uring/fs: consider link->flags when getting path for LINKAT
Date: Mon, 20 Nov 2023 05:55:45 -0500 [thread overview]
Message-ID: <[email protected]> (raw)
In order for `AT_EMPTY_PATH` to work as expected, the fact
that the user wants that behavior needs to make it to `getname_flags`
or it will return ENOENT.
Fixes: cf30da90bc3a ("io_uring: add support for IORING_OP_LINKAT")
