After sending the reboot command, we need to wait briefly for it to be
rebooted so that the kernel client doesn't voluntarily give up its Fb
cap.

These configs were used for initialization but it is more appropriate to
require setting these file system attributes via `ceph fs set`. This is similar
to what was already done with max_mds. There are new variables added for `fs
set` where missing.

When selinux is enabled, kernel client may releases inodes (without
uptodate xattr) in readdir reply immediately after processing the reply.
The reason is that linking the inode to dentry causes deadlock if xattr
is not uptodate.
We can use stat(2) syscall to guarantee that kernel client caches an
inode.
