Subject: [PATCH 1/5] 9pfs: fix qemu_mknodat(S_IFREG) on macOS
Date: Tue, 19 Apr 2022 13:40:48 +0200 [thread overview]
Message-ID: <2a515431fdc02b0b2d3613f5d569305a32cfba30.1650370026.git.qemu_oss@crudebyte.com> (raw)
In-Reply-To: <cover.1650370026.git.qemu_oss@crudebyte.com>
mknod() on macOS does not support creating regular files, so
divert to openat_file() if S_IFREG is passed with mode argument.
Furthermore, 'man 2 mknodat' on Linux says: "Zero file type is
equivalent to type S_IFREG".
