Subject: mm: move mmap_init_lock() out of the header file
has been removed from the -mm tree. Its filename was
mm-move-mmap_init_lock-out-of-the-header-file.patch
This patch was dropped because it was merged into the mm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: mm: move mmap_init_lock() out of the header file
Date: Thu, 13 Feb 2025 14:46:45 -0800
mmap_init_lock() is used only from mm_init() in fork.c, therefore it does
not have to reside in the header file. This move lets us avoid including
additional headers in mmap_lock.h later, when mmap_init_lock() needs to
initialize rcuwait object.
