parentmnt: Add a per mount namespace limit on the number of mounts (diff)
autofs: Fix automounts by using current_real_cred()->uid
Seth Forshee reports that in 4.8-rcN some automounts are failing because the requesting the automount changed. The relevant call path is: follow_automount() ->d_automount autofs4_d_automount autofs4_mount_wait autofs4_wait In autofs4_wait wq_uid and wq_gid are set to current_uid() and current_gid respectively. With follow_automount now overriding creds uid that we export to userspace changes and that breaks existing setups. To remove the regression set wq_uid and wq_gid from current_real_cred()->uid and current_real_cred()->gid respectively. This restores the current behavior as current->real_cred is identical to current->cred except when override creds are used.
