[PATCH] percpu: make pcpu_alloc_chunk() use pcpu_mem_free() instead of kfree()

pcpu_chunk_struct_size = sizeof(struct pcpu_chunk) + BITS_TO_LONGS(pcpu_unit_pages) * sizeof(unsigned long) It hardly could be ever bigger than PAGE_SIZE even for large-scale machine, but for consistency with its couterpart pcpu_mem_zalloc(), use pcpu_mem_free() instead. Commit

Linux 3.15-rc1 out, merge window closed

It's been two weeks since 3.14 was released, and -rc1 of 3.15 is now tagged and pushed out, and the patches and tar-balls are going through the compressors on kernel.org as I write this. Which means that the merge window is closed, and people should send me fixes only. And quite frankly, it's

[PATCH v3 3/7] Factor page_endio() out of mpage_end_io()

page_endio() takes care of updating all the appropriate page flags once I/O has finished to a page. Switch to using mapping_set_error() instead of setting AS_EIO directly; this will handle thin-provisioned devices correctly. Signed-off-by: Matthew Wilcox --- fs/mpage.c | 18

[PATCH v3 4/7] Add bdev_read_page() and bdev_write_page()

A block device driver may choose to provide a rw_page operation. These will be called when the filesystem is attempting to do page sized I/O to page cache pages (ie not for direct I/O). This does preclude I/Os that are larger than page size, so this may only be a performance gain for some

[PATCH v3 1/7] Remove block_write_full_page_endio()

The last in-tree caller of block_write_full_page_endio() was removed in January 2013. It's time to remove the EXPORT_SYMBOL, which leaves block_write_full_page() as the only caller of block_write_full_page_endio(), so inline block_write_full_page_endio() into block_write_full_page().
