2020-05-11f2fs: compress: support lzo-rle compress algorithmChao Yu1-1/+1
LZO-RLE extension (run length encoding) was introduced to improve performance of LZO algorithm in scenario of data contains many zeros, zram has changed to use this extended algorithm by default, this patch adds to support this algorithm extension, to enable this extension, it needs to enable F2FS_FS_LZO and F2FS_FS_LZORLE config, and specifies "compress_algorithm=lzo-rle" mountoption.

2020-05-08nfsd: clients don't need to break their own delegationsJ. Bruce Fields1-0/+2
We currently revoke read delegations on any write open or any operation that modifies file data or metadata (including rename, link, and unlink). But if the delegation in question is the only read delegation and is held by the client performing the operation, that's not really necessary. It's not always possible to prevent this in the NFSv4.0 case, because there's not always a way to determine which client an NFSv4.0 delegation came from. (In theory we could try to guess this from the transport layer, e.g., by assuming all traffic on a given TCP connection comes from the same client. But that's not really correct.) In the NFSv4.1 case the session layer always tells us the client. This patch should remove such self-conflicts in all cases where we can reliably determine the client from the compound. To do that we need to track "who" is performing a given (possibly lease-breaking) file operation. We're doing that by storing the information in the svc_rqst and using kthread_data() to map the current task back to a svc_rqst. Signed-off-by: J. Bruce Fields <bfields@redhat.com>

2020-04-22proc: use human-readable values for hidepidAlexey Gladkov1-26/+26
The hidepid parameter values are becoming more and more and it becomes difficult to remember what each new magic number means. Backward compatibility is preserved since it is possible to specify numerical value for the hidepid parameter. This does not break the fsconfig since it is not possible to specify a numerical value through it. All numeric values are converted to a string. The type FSCONFIG_SET_BINARY cannot be used to indicate a numerical value. Selftest has been added to verify this behavior.

Pull orangefs updates from Mike Marshall: "A fix and two cleanups. Fix: - Christoph Hellwig noticed that some logic I added to orangefs_file_read_iter introduced a race condition, so he sent a reversion patch. I had to modify his patch since reverting at this point broke Orangefs. Cleanups: - Christoph Hellwig noticed that we were doing some unnecessary work in orangefs_flush, so he sent in a patch that removed the un-needed code. - Al Viro told me he had trouble building Orangefs. Orangefs should be easy to build, even for Al :-). I looked back at the test server build notes in orangefs.txt, just in case that's where the trouble really is, and found a couple of typos and made a couple of clarifications" * tag 'for-linus-5.7-ofs1' of git://git.kernel.org/pub/scm/linux/kernel/git/hubcap/linux: orangefs: clarify build steps for test server in orangefs.txt orangefs: don't mess with I_DIRTY_TIMES in orangefs_flush orangefs: get rid of knob code...

Pull ceph updates from Ilya Dryomov: "The main items are: - support for asynchronous create and unlink (Jeff Layton). Creates and unlinks are satisfied locally, without waiting for a reply from the MDS, provided the client has been granted appropriate caps (new in v15.y.z ("Octopus") release). This can be a big help for metadata heavy workloads such as tar and rsync. Opt-in with the new nowsync mount option. - multiple blk-mq queues for rbd (Hannes Reinecke and myself). When the driver was converted to blk-mq, we settled on a single blk-mq queue because of a global lock in libceph and some other technical debt. These have since been addressed, so allocate a queue per CPU to enhance parallelism. - don't hold onto caps that aren't actually needed (Zheng Yan). This has been our long-standing behavior, but it causes issues with some active/standby applications (synchronous I/O, stalls if the standby goes down, etc). - .snap directory timestamps consistent with ceph-fuse (Luis Henriques)" * tag 'ceph-for-5.7-rc1' of git://github.com/ceph/ceph-client: (49 commits) ceph: fix snapshot directory timestamps ceph: wait for async creating inode before requesting new max size ceph: don't skip updating wanted caps when cap is stale ceph: request new max size only when there is auth cap ceph: cleanup return error of try_get_cap_refs() ceph: return ceph_mdsc_do_request() errors from __get_parent() ceph: check all mds' caps after page writeback ceph: update i_requested_max_size only when sending cap msg to auth mds ceph: simplify calling of ceph_get_fmode() ceph: remove delay check logic from ceph_check_caps() ceph: consider inode's last read/write when calculating wanted caps ceph: always renew caps if mds_wanted is insufficient ceph: update dentry lease for async create ceph: attempt to do async create when possible ceph: cache layout in parent dir on first sync create ceph: add new MDS req field to hold delegated inode number ceph: decode interval_sets for delegated inos ceph: make ceph_fill_inode non-static ceph: perform asynchronous unlink if we have sufficient caps ceph: don't take refs to want mask unless we have all bits ...

Regular files opened with O_NONBLOCK allow read to return after a single round-trip with the server instead of trying to fill buffer. Add a few lines in 9p documentation to describe that.
