Hello Jeff Layton,
The patch d6566c62c529: "ceph: perform asynchronous unlink if we have
sufficient caps" from Apr 2, 2019, leads to the following static
checker warning:
fs/ceph/dir.c:1059 get_caps_for_async_unlink()
error: uninitialized symbol 'got'.
fs/ceph/dir.c
1051 static bool get_caps_for_async_unlink(struct inode *dir, struct dentry *dentry)
1052 {
1053 struct ceph_inode_info *ci = ceph_inode(dir);
1054 struct ceph_dentry_info *di;
1055 int ret, want, got;
1056
1057 want = CEPH_CAP_FILE_EXCL | CEPH_CAP_DIR_UNLINK;
1058 ret = ceph_try_get_caps(dir, 0, want, true, &got);
1059 dout("Fx on %p ret=%d got=%d\n", dir, ret, got);
^^^
Uninitialized on error.
1060 if (ret != 1 || got != want)
1061 return false;
