[PATCHv3 01/11] USB: gadget: g_mass_storage: static data instead of dynamic allocation
This patch changes msg_do_config() function so that it uses a static object for a fsg_common structure instead of dynamically allocated. This is a micro-optimisation.

kconfig: introduce nonint_oldconfig and loose_nonint_oldconfig (v3)

[PATCH 18/21] Hibernation: Remove wait_on_bio_chain result
wait_on_bio_chain can't fail - make the result void instead of int.

Nigel's current for-rafael queue
Hi all. Here is my current patch queue. Taken together, the patches implement the separation of low level block i/o into a separate file, switch from using swap_map_pages to extents stores prior to the 'header' page and implement fully asynchronous (rather than batched I/O). I have only run it under VMware so... 2 Jun 2010 08:43

[PATCH 09/21] Hibernation: Stop passing bio_chain around
Stop using the struct bio **bio_chain as a means of tracking outstanding i/o and signalling when we want synchronous i/o. Instead, keep a bio_chain in the block_io code and use a flag to explicitly request synchronous I/O.

[PATCH 01/21] Hibernation: Swap iteration functions.
Add the data structure 'storage_position' and routines that allow a caller to iterate over swap in sector order. Note that calling reset_storage_pos only resets the position. next_swapdev_block must also be called to get the address of the first (and subsequent sectors).

[PATCH 21/21] Hibernation: Remove now-empty routines.
release_swap_writer and release_swap_reader are now empty functions. Remove them and clean up callers (including swap_reader_finish, which just called release_swap_reader).

[PATCH 14/21] Hibernation: Use block extents for reading image

[PATCH 11/21] Hibernation: Partial page I/O support.
Add functions that can be used for coalescing and splitting buffers that are smaller than PAGE_SIZE. These functions provide no method of determining where the boundaries of the smaller buffers are to be found - that is the caller's problem.
