Merge tag 'for-linus-5.2-ofs1' of git://git.kernel.org/pub/scm/linux/kernel/git/hubcap/linux
Pull orangefs updates from Mike Marshall: "This includes one fix and our "Orangefs through the pagecache" patch series which greatly improves our small IO performance and helps us pass more xfstests than before. Fix: - orangefs: truncate before updating size Pagecache series: - all the rest" * tag 'for-linus-5.2-ofs1' of git://git.kernel.org/pub/scm/linux/kernel/git/hubcap/linux: (23 commits) orangefs: truncate before updating size orangefs: copy Orangefs-sized blocks into the pagecache if possible. orangefs: pass slot index back to readpage. orangefs: remember count when reading. orangefs: add orangefs_revalidate_mapping orangefs: implement writepages orangefs: write range tracking orangefs: avoid fsync service operation on flush orangefs: skip inode writeout if nothing to write orangefs: move do_readv_writev to direct_IO orangefs: do not return successful read when the client-core disappeared orangefs: implement writepage orangefs: migrate to generic_file_read_iter orangefs: service ops done for writeback are not killable orangefs: remove orangefs_readpages orangefs: reorganize setattr functions to track attribute changes orangefs: let setattr write to cached inode orangefs: set up and use backing_dev_info orangefs: hold i_lock during inode_getattr orangefs: update attributes rather than relying on server ...
