Merge tag 'fuse-update-4.20' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse
Pull fuse updates from Miklos Szeredi: "As well as the usual bug fixes, this adds the following new features: - cached readdir and readlink - max I/O size increased from 128k to 1M - improved performance and scalability of request queues - copy_file_range support The only non-fuse bits are trivial cleanups of macros in <linux/bitops.h>" * tag 'fuse-update-4.20' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse: (31 commits) fuse: enable caching of symlinks fuse: only invalidate atime in direct read fuse: don't need GETATTR after every READ fuse: allow fine grained attr cache invaldation bitops: protect variables in bit_clear_unless() macro bitops: protect variables in set_mask_bits() macro fuse: realloc page array fuse: add max_pages to init_out fuse: allocate page array more efficiently fuse: reduce size of struct fuse_inode fuse: use iversion for readdir cache verification fuse: use mtime for readdir cache verification fuse: add readdir cache version fuse: allow using readdir cache fuse: allow caching readdir fuse: extract fuse_emit() helper fuse: add FOPEN_CACHE_DIR fuse: split out readdir.c fuse: Use hash table to link processing request fuse: kill req->intr_unique ...
