xfs: buffer cache bulk page allocation This patchset makes use of the new bulk page allocation interface to reduce the overhead of allocating large numbers of pages in a loop. The first two patches are refactoring buffer memory allocation and converting the uncached buffer path to use the same page allocation path, followed by converting the page allocation path to use bulk allocation. The rest of the patches are then consolidation of the page allocation and freeing code to simplify the code and remove a chunk of unnecessary abstraction. This is largely based on a series of changes made by Christoph Hellwig. * tag 'xfs-buf-bulk-alloc-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs: xfs: merge xfs_buf_allocate_memory xfs: cleanup error handling in xfs_buf_get_map xfs: get rid of xb_to_gfp() xfs: simplify the b_page_count calculation xfs: remove ->b_offset handling for page backed buffers xfs: move page freeing into _xfs_buf_free_pages() xfs: merge _xfs_buf_get_pages() xfs: use alloc_pages_bulk_array() for buffers xfs: use xfs_buf_alloc_pages for uncached buffers xfs: split up xfs_buf_allocate_memory
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
