Subject[PATCH] io_uring/fs: consider link->flags when getting path for LINKAT
Date
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")
