To better handle full clusters/pools in the osd_client, we need to be able to issue continuous osdmap subs. Revamp subs code to allow us to specify for each sub whether it should be continuous or not. Although not strictly required for the above, switch to SUBSCRIBE2 protocol while at it, eliminating the ambiguity between a request for "every map since X" and a request for "just the latest" when we don't have a map yet (i.e. have epoch 0). SUBSCRIBE2 feature bit is now required - it's been supported since pre-argonaut (2010). Move "got mdsmap" call to the end of ceph_mdsc_handle_map() - calling in before we validate the epoch and successfully install the new map can mess up mon_client sub state.

Clear hunting when we complete the authentication handshake.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Our debugfs dir name is a concatenation of cluster fsid and client unique ID ("global_id"). It used to be the case that we learned global_id first, nowadays we always learn fsid first - the monmap is sent before any auth replies are. ceph_debugfs_client_init() call in ceph_monc_handle_map() is therefore never executed and can be removed. Its counterpart in handle_auth_reply() doesn't really belong there either: having to do monc->client and unlocking early to work around lockdep is a testament to that. Move it into __ceph_open_session(), where it can be called unconditionally.

This finally merges the long-pending orangefs filesystem, which has been much cleaned up with input from Al Viro over the last six months. From the documentation file: "OrangeFS is an LGPL userspace scale-out parallel storage system. It is ideal for large storage problems faced by HPC, BigData, Streaming Video, Genomics, Bioinformatics. Orangefs, originally called PVFS, was first developed in 1993 by Walt Ligon and Eric Blumer as a parallel file system for Parallel Virtual Machine (PVM) as part of a NASA grant to study the I/O patterns of parallel programs. Orangefs features include: - Distributes file data among multiple file servers - Supports simultaneous access by multiple clients - Stores file data and metadata on servers using local file system and access methods - Userspace implementation is easy to install and maintain - Direct MPI support - Stateless" see Documentation/filesystems/orangefs.txt for more in-depth details. * tag 'ofs-pull-tag-1' of git://git.kernel.org/pub/scm/linux/kernel/git/hubcap/linux: (174 commits) orangefs: fix orangefs_superblock locking orangefs: fix do_readv_writev() handling of error halfway through orangefs: have ->kill_sb() evict the VFS side of things first orangefs: sanitize ->llseek() orangefs-bufmap.h: trim unused junk orangefs: saner calling conventions for getting a slot orangefs_copy_{to,from}_bufmap(): don't pass bufmap pointer orangefs: get rid of readdir_handle_s ornagefs: ensure that truncate has an up to date inode size orangefs: move code which sets i_link to orangefs_inode_getattr orangefs: remove needless wrapper around GFP_KERNEL orangefs: remove wrapper around mutex_lock(&inode->i_mutex) orangefs: refactor inode type or link_target change detection orangefs: use new getattr for revalidate and remove old getattr orangefs: use new getattr in inode getattr and permission orangefs: use new orangefs_inode_getattr to get size in write and llseek orangefs: use new orangefs_inode_getattr to create new inodes orangefs: rename orangefs_inode_getattr to orangefs_inode_old_getattr orangefs: remove inode->i_lock wrapper orangefs: put register_chrdev immediately before register_filesystem ... | * | orangefs: fix orangefs_superblock lockingAl Viro2016-03-263-58/+47

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * switch orangefs_remount() to taking ORANGEFS_SB(sb) instead of sb * remove from the list _before_ orangefs_unmount() - request_mutex in the latter will make sure that nothing observed in the loop in ORANGEFS_DEV_REMOUNT_ALL handling will get freed until the end of loop * on removal, keep the forward pointer and zero the back one. That way we can drop and regain the spinlock in the loop body (again, ORANGEFS_DEV_REMOUNT_ALL one) and still be able to get to the rest of the list.
