From 083d633756c23c237724703956208e3067372ea8 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Thu, 6 Feb 2020 21:42:51 -0700 Subject: [PATCH 1224/2944] io_uring: allow AT_FDCWD for non-file openat/openat2/statx to #26323588 commit 0b5faf6ba7fb78bb1fe7336d23ea1978386a6c3a upstream. Don't just check for dirfd == -1, we should allow AT_FDCWD as well for relative lookups.
