The system-wide registry of syntax types (string/enum/int32/oct32/.../etc.) is gone and so is the horror switch() in fs_parse() that would have to grow another case every time something got added to that system-wide registry. New syntax types can be added by filesystems easily now, and their namespace is that of functions - not of system-wide enum members. IOW, they can be shared or kept private and if some turn out to be widely useful, we can make them common library helpers, etc., without having to do anything whatsoever to fs_parse() itself. And we already get that kind of requests - the thing that finally pushed me into doing that was "oh, and let's add one for timeouts - things like 15s or 2h". If some filesystem really wants that, let them do it. Without somebody having to play gatekeeper for the variants blessed by direct support in fs_parse(), TYVM. Quite a bit of boilerplate is gone. And IMO the data structures make a lot more sense now. -200LoC, while we are at it" * 'merge.nfs-fs_parse.1' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: (25 commits) tmpfs: switch to use of invalfc() cgroup1: switch to use of errorfc() et.al. procfs: switch to use of invalfc() hugetlbfs: switch to use of invalfc() cramfs: switch to use of errofc() et.al. gfs2: switch to use of errorfc() et.al. fuse: switch to use errorfc() et.al. ceph: use errorfc() and friends instead of spelling the prefix out prefix-handling analogues of errorf() and friends turn fs_param_is_... into functions fs_parse: handle optional arguments sanely fs_parse: fold fs_parameter_desc/fs_parameter_spec fs_parser: remove fs_parameter_description name field add prefix to fs_context->log ceph_parse_param(), ceph_parse_mon_ips(): switch to passing fc_log new primitive: __fs_parse() switch rbd and libceph to p_log-based primitives struct p_log, variants of warnf() et.al. taking that one instead teach logfc() to handle prefices, give it saner calling conventions get rid of cg_invalf() ... 2020-02-07T20:26:34+00:00 Linus Torvalds torvalds@linux-foundation.org 2020-02-07T20:26:34+00:00 urn:sha1:e0f121c5cc2cf079d13ebe65b490ca88ba6abe12 Pull virtio updates from Michael Tsirkin: "Some bug fixes/cleanups.

To make it even more unpleasant, that combination is impossible to produce with fsconfig(). Much saner rules would be "foo" => fs_value_is_flag, NULL "foo=" => fs_value_is_string, "" "foo=bar" => fs_value_is_string, "bar" All cases are distinguishable, all results are expressable by fsconfig(), ->has_value checks are much simpler that way (to the point of the field being useless) and quite a few regressions go away (gfs2 has no business accepting -o nodebug=, for example). Partially based upon patches from Miklos.

This has to do with choosing an MDS, distinguishing between laggy and down MDSes and parsing the server path. - inode initialization fixes (Jeff Layton). The one included here mostly concerns things like open_by_handle() and there is another one that will come through Al. - copy_file_range() now uses the new copy-from2 op (Luis Henriques). The existing copy-from op turned out to be infeasible for generic filesystem use; we disable the copy offload if OSDs don't support copy-from2. - a patch to link "rbd" and "block" devices together in sysfs (Hannes Reinecke) ... and a smattering of cleanups from Xiubo, Jeff and Chengguang. * tag 'ceph-for-5.6-rc1' of https://github.com/ceph/ceph-client: (25 commits) rbd: set the 'device' link in sysfs ceph: move net/ceph/ceph_fs.c to fs/ceph/util.c ceph: print name of xattr in __ceph_{get,set}xattr() douts ceph: print r_direct_hash in hex in __choose_mds() dout ceph: use copy-from2 op in copy_file_range ceph: close holes in structs ceph_mds_session and ceph_mds_request rbd: work around -Wuninitialized warning ceph: allocate the correct amount of extra bytes for the session features ceph: rename get_session and switch to use ceph_get_mds_session ceph: remove the extra slashes in the server path ceph: add possible_max_rank and make the code more readable ceph: print dentry offset in hex and fix xattr_version type ceph: only touch the caps which have the subset mask requested ceph: don't clear I_NEW until inode metadata is fully populated ceph: retry the same mds later after the new session is opened ceph: check availability of mds cluster on mount after wait timeout ceph: keep the session state until it is released ceph: add __send_request helper ceph: ensure we have a new cap before continuing in fill_inode ceph: drop unused ttl_from parameter from fill_inode ... 2020-02-06T08:40:26+00:00 Christoph Hellwig hch@lst.de 2019-12-12T16:37:19+00:00 urn:sha1:782e067dba52de989a445f1bfa4bb770abb34480 Since the need for a special flag to support SCSI passthrough on a block device was added in May 2017 the SCSI passthrough support in virtio-blk has been disabled. It has always been a bad idea (just ask the original author..) and we have virtio-scsi for proper passthrough. The feature also never made it into the virtio 1.0 or later specifications.
