Subject: [PATCH 00/17] orangefs: page cache
Date: Mon, 17 Sep 2018 20:10:37 +0000	[thread overview]
Message-ID: <20180917201054.3530-1-martin@omnibond.com> (raw)

If no major issues are found in review or in our testing, we intend to
submit this during the next merge window.

The goal of all this is to significantly reduce the number of network
requests made to the OrangeFS

First the xattr cache is needed because otherwise we make a ton of
getxattr calls from security_inode_need_killpriv.

Then there's some reorganization so inode changes can be cached.
Finally, we enable write_inode.

Then remove the old readpages.  Next there's some reorganization to
support readpage/writepage.  Finally, enable readpage/writepage which
is fairly straightforward except for the need to separate writes from
different uid/gid pairs due to the design of our server.

Martin Brandenburg (17):
  orangefs: implement xattr cache
  orangefs: do not invalidate attributes on inode create
  orangefs: simply orangefs_inode_getattr interface
  orangefs: update attributes rather than relying on server
  orangefs: hold i_lock during inode_getattr
  orangefs: set up and use backing_dev_info
  orangefs: let setattr write to cached inode
  orangefs: reorganize setattr functions to track attribute changes
  orangefs: remove orangefs_readpages
  orangefs: service ops done for writeback are not killable
  orangefs: migrate to generic_file_read_iter
  orangefs: implement writepage
  orangefs: skip inode writeout if nothing to write
  orangefs: write range tracking
  orangefs: avoid fsync service operation on flush
  orangefs: use kmem_cache for orangefs_write_request
  orangefs: implement writepages
