[PATCH 09/14] vmscan: Setup pagevec as late as possible in shrink_inactive_list()
shrink_inactive_list() sets up a pagevec to release unfreeable pages. It uses significant amounts of stack doing this. This patch splits shrink_inactive_list() to take the stack usage out of the main path so that callers to writepage() do not contain an unused pagevec on the stack.

[PATCH 3/3] splice: fix misuse of SPLICE_F_NONBLOCK
From: Miklos Szeredi <mszeredi(a)suse.cz> SPLICE_F_NONBLOCK is clearly documented to only affect blocking on the destination pipe and not on the source file. In __generic_file_splice_read(), however, it returns EAGAIN if the page is currently being read. This makes it impossible to write an application that on... 29 Jun 2010 07:27

[PATCH 1/3] splice: direct_splice_actor() should not use pos in sd
From: Changli Gao <xiaosuo(a)gmail.com> direct_splice_actor() shouldn't use sd->pos, as sd->pos is for file reading, file->f_pos should be used instead.
