The patch titled
Subject: usermodehelper: kill umh_wait, renumber UMH_* constants
has been removed from the -mm tree. Its filename was
usermodehelper-kill-umh_wait-renumber-umh_-constants.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/

Subject: usermodehelper: kill umh_wait, renumber UMH_* constants
No functional changes. It is not sane to use UMH_KILLABLE with enum
umh_wait, but obviously we do not want another argument in
call_usermodehelper_* helpers. Kill this enum, use the plain int.
