Pull f2fs updates from Jaegeuk Kim: "In this round, we've introduced native swap file support which can exploit DIO, enhanced existing checkpoint=disable feature with additional mount option to tune the triggering condition, and allowed user to preallocate physical blocks in a pinned file which will be useful to avoid f2fs fragmentation in append-only workloads. In addition, we've fixed subtle quota corruption issue. Enhancements: - add swap file support which uses DIO - allocate blocks for pinned file - allow SSR and mount option to enhance checkpoint=disable - enhance IPU IOs - add more sanity checks such as memory boundary access Bug fixes: - quota corruption in very corner case of error-injected SPO case - fix root_reserved on remount and some wrong counts - add missing fsck flag Some patches were also introduced to clean up ambiguous i_flags and debugging messages codes" * tag 'f2fs-for-5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs: (33 commits) f2fs: improve print log in f2fs_sanity_check_ckpt() f2fs: avoid out-of-range memory access f2fs: fix to avoid long latency during umount f2fs: allow all the users to pin a file f2fs: support swap file w/ DIO f2fs: allocate blocks for pinned file f2fs: fix is_idle() check for discard type f2fs: add a rw_sem to cover quota flag changes f2fs: set SBI_NEED_FSCK for xattr corruption case f2fs: use generic EFSBADCRC/EFSCORRUPTED f2fs: Use DIV_ROUND_UP() instead of open-coding f2fs: print kernel message if filesystem is inconsistent f2fs: introduce f2fs_ macros to wrap f2fs_printk() f2fs: avoid get_valid_blocks() for cleanup f2fs: ioctl for removing a range from F2FS f2fs: only set project inherit bit for directory f2fs: separate f2fs i_flags from fs_flags and ext4 i_flags f2fs: replace ktype default_attrs with default_groups f2fs: Add option to limit required GC for checkpoint=disable f2fs: Fix accounting for unusable blocks ...

block: add a report_zones method

2018-10-25T17:17:40+00:00

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

2018-03-28T20:55:18+00:00

- 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
