Equivalent transformation - the only place in __get_user_pages_locked()
where we look at notify_drop argument is
if (notify_drop && lock_dropped && *locked) {
up_read(&mm->mmap_sem);
*locked = 0;
}
in the very end. Changing notify_drop from false to true won't change
behaviour unless *locked is non-zero. The caller is
ret = __get_user_pages_locked(current, mm, start, nr_pages, pages, NULL,
&locked, false, gup_flags | FOLL_TOUCH);
if (locked)
up_read(&mm->mmap_sem);
so in that case the original kernel would have done up_read() right after
return from __get_user_pages_locked(), while the modified one would've done
it right before the return.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
