block: add a report_zones method

2018-10-25T17:17:40Z

Dispatching a report zones command through the request queue is a major pain due to the command reply payload rewriting necessary. Given that blkdev_report_zones() is executing everything synchronously, implement report zones as a block device file operation instead, allowing major simplification of the code in many places. sd, null-blk, dm-linear and dm-flakey being the only block device drivers supporting exposing zoned block devices, these drivers are modified to provide the device side implementation of the report_zones() block device file operation. For device mappers, a new report_zones() target type operation is defined so that the upper block layer calls blkdev_report_zones() can be propagated down to the underlying devices of the dm targets. Implementation for this new operation is added to the dm-linear and dm-flakey targets.

treewide: remove large struct-pass-by-value from tracepoint arguments

2018-03-28T20:55:18Z

- fix trace_hfi1_ctxt_info() to pass large struct by reference instead of by value - convert 'type array[]' tracepoint arguments into 'type *array', since compiler will warn that sizeof('type array[]') == sizeof('type *array') and later should be used instead The CAST_TO_U64 macro in the later patch will enforce that tracepoint arguments can only be integers, pointers, or less than 8 byte structures. Larger structures should be passed by reference. Signed-off-by: Alexei Starovoitov Signed-off-by: Daniel Borkmann

f2fs: recover directory operations by fsync

2017-11-16T20:10:21Z

Pull f2fs updates from Jaegeuk Kim: "In this round, we introduce sysfile-based quota support which is required for Android by default. In addition, we allow that users are able to reserve some blocks in runtime to mitigate performance drops in low free space. Enhancements: - assign proper data segments according to write_hints given by user - issue cache_flush on dirty devices only among multiple devices - exploit cp_error flag and add more faults to enhance fault injection test - conduct more readaheads during f2fs_readdir - add a range for discard commands Bug fixes: - fix zero stat->st_blocks when inline_data is set - drop crypto key and free stale memory pointer while evict_inode is failing - fix some corner cases in free space and segment management - fix wrong last_disk_size This series includes lots of clean-ups and code enhancement in terms of xattr operations, discard/flush command control. In addition, it adds versatile debugfs entries to monitor f2fs status" * tag 'f2fs-for-4.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs: (75 commits) f2fs: deny accessing encryption policy if encryption is off f2fs: inject fault in inc_valid_node_count f2fs: fix to clear FI_NO_PREALLOC f2fs: expose quota information in debugfs f2fs: separate nat entry mem alloc from nat_tree_lock f2fs: validate before set/clear free nat bitmap f2fs: avoid opened loop codes in __add_ino_entry f2fs: apply write hints to select the type of segments for buffered write f2fs: introduce scan_curseg_cache for cleanup f2fs: optimize the way of traversing free_nid_bitmap f2fs: keep scanning until enough free nids are acquired f2fs: trace checkpoint reason in fsync() f2fs: keep isize once block is reserved cross EOF f2fs: avoid race in between GC and block exchange f2fs: save a multiplication for last_nid calculation f2fs: fix summary info corruption f2fs: remove dead code in update_meta_page f2fs: remove unneeded semicolon f2fs: don't bother with inode->i_version f2fs: check curseg space before foreground GC ...

f2fs: trace checkpoint reason in fsync()
