The patch titled
Subject: mm/shmem.c: fix unused shmem_parse_huge() function warning
has been removed from the -mm tree. Its filename was
thp-fix-unused-shmem_parse_huge-function-warning.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Arnd Bergmann <arnd@xxxxxxxx>
Subject: mm/shmem.c: fix unused shmem_parse_huge() function warning
When CONFIG_SYSFS is disabled but CONFIG_TMPFS is enabled, we get a
warning about shmem_parse_huge() never being called:
mm/shmem.c:417:12: error: unused function 'shmem_parse_huge' [-Werror,-Wunused-function]
static int shmem_parse_huge(const char *str)
Change the #ifdef so we no longer build this function in that configuration.
Link: http://lkml.kernel.org/r/20190712091141.673355-1-arnd@xxxxxxxx
Fixes: 144df3b288c4 ("vfs: Convert ramfs, shmem, tmpfs, devtmpfs, rootfs to use the new mount API")
