Hi Darrick, As we talked about on IRC, I have (force) updated the branch and tag containing the buffer cache bulk page allocation series to correct the errors in the commit metadata. This version correctly attributes all of Christoph's patches, fixes a couple of minor typos and adds a missing committer SoB to another of Christoph's patches. There are no code changes in this update. When you next update the for-next branch, can you please pull the updates from the tag below? Cheers, Dave. The following changes since commit d07f6ca923ea0927a1024dfccafc5b53b61cfecc: Linux 5.13-rc2 (2021-05-16 15:27:44 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs.git tags/xfs-buf-bulk-alloc-tag for you to fetch changes up to 8bcac7448a942fa4662441a310c97d47cec24310: xfs: merge xfs_buf_allocate_memory (2021-06-07 11:50:48 +1000) ---------------------------------------------------------------- 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. ---------------------------------------------------------------- Christoph Hellwig (3): xfs: remove ->b_offset handling for page backed buffers xfs: simplify the b_page_count calculation xfs: cleanup error handling in xfs_buf_get_map Dave Chinner (7): xfs: split up xfs_buf_allocate_memory xfs: use xfs_buf_alloc_pages for uncached buffers xfs: use alloc_pages_bulk_array() for buffers xfs: merge _xfs_buf_get_pages() xfs: move page freeing into _xfs_buf_free_pages() xfs: get rid of xb_to_gfp() xfs: merge xfs_buf_allocate_memory fs/xfs/libxfs/xfs_ag.c | 1 - fs/xfs/xfs_buf.c | 305 ++++++++++++++++++++++++++++++++++++++++++++++------------------------------------------------------------------------- fs/xfs/xfs_buf.h | 3 +- 3 files changed, 120 insertions(+), 189 deletions(-)
