The patch titled
shmem: SGP_QUICK and SGP_FAULT redundant
has been removed from the -mm tree. Its filename was
shmem-sgp_quick-and-sgp_fault-redundant.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: shmem: SGP_QUICK and SGP_FAULT redundant
From: Hugh Dickins <hugh@xxxxxxxxxxx>
Remove SGP_QUICK from the sgp_type enum: it was for shmem_populate and has no
users now. Remove SGP_FAULT from the enum: SGP_CACHE does just as well (and
shmem_getpage is about to return with page always locked).
