Hello Jeff Layton,
The patch 9a8d03ca2e2c: "ceph: attempt to do async create when
possible" from Nov 27, 2019, leads to the following static checker
warning:
fs/ceph/file.c:540 ceph_async_create_cb()
error: uninitialized symbol 'base'.
fs/ceph/file.c
526 mapping_set_error(req->r_parent->i_mapping, result);

528 if (result) {

530 int pathlen;
531 u64 base;

533 &base, 0);
