2014-08-06	mm: describe mmap_sem rules for __lock_page_or_retry() and callers	Paul Cassella	1	-3/+15
	Add a comment describing the circumstances in which __lock_page_or_retry() will or will not release the mmap_sem when returning 0. Add comments to lock_page_or_retry()'s callers (filemap_fault(), do_swap_page()) noting the impact on VM_FAULT_RETRY returns. Add comments on up the call tree, particularly replacing the false "We return with mmap_sem still held" comments.

2014-06-04	mm: cleanup __get_user_pages()	Kirill A. Shutemov	1	-111/+107
	Get rid of two nested loops over nr_pages, extract vma flags checking to separate function and other random cleanups. Signed-off-by: Kirill A.

2014-06-04	mm: extract code to fault in a page from __get_user_pages()	Kirill A. Shutemov	1	-67/+71
	Nesting level in __get_user_pages() is just insane. Let's try to fix it a bit. Signed-off-by: Kirill A. Shutemov <kirill.shutemov@linux.intel.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2014-06-04	mm: cleanup follow_page_mask()	Kirill A. Shutemov	1	-112/+119
	Cleanups: - move pte-related code to separate function. It's about half of the function; - get rid of some goto-logic; - use 'return NULL' instead of 'return page' where page can only be NULL; Signed-off-by: Kirill A.

2014-06-04	mm: extract in_gate_area() case from __get_user_pages()	Kirill A. Shutemov	1	-42/+48
	The case is special and disturb from reading main __get_user_pages() code path. Let's move it to separate function. Signed-off-by: Kirill A.

2014-06-04	mm: move get_user_pages()-related code to separate file	Kirill A. Shutemov	1	-0/+649
	mm/memory.c is overloaded: over 4k lines. get_user_pages() code is pretty much self-contained let's move it to separate file. No other changes made. Signed-off-by: Kirill A.
