tracing: Add #undef to fix compile error

2017-03-18T11:14:29Z

commit bf7165cfa23695c51998231c4efa080fe1d3548d upstream. There are several trace include files that define TRACE_INCLUDE_FILE. Include several of them in the same .c file (as I currently have in some code I am working on), and the compile will blow up with a "warning: "TRACE_INCLUDE_FILE" redefined #define TRACE_INCLUDE_FILE syscalls" Every other include file in include/trace/events/ avoids that issue by having a #undef TRACE_INCLUDE_FILE before the #define; syscalls.h should have one, too.

swiotlb: Add swiotlb=noforce debug option

2017-01-26T07:24:44Z

commit fff5d99225107f5f13fe4a9805adc2a1c4b5fb00 upstream. On architectures like arm64, swiotlb is tied intimately to the core architecture DMA support. In addition, ZONE_DMA cannot be disabled. To aid debugging and catch devices not supporting DMA to memory outside the 32-bit address space, add a kernel command line option "swiotlb=noforce", which disables the use of bounce buffers. If specified, trying to map memory that cannot be used with DMA will fail, and a rate-limited warning will be printed. Note that io_tlb_nslabs is set to 1, which is the minimal supported value.

swiotlb: Convert swiotlb_force from int to enum

2017-01-26T07:24:44Z

commit ae7871be189cb41184f1e05742b4a99e2c59774d upstream. Convert the flag swiotlb_force from an int to an enum, to prepare for the advent of more possible values.

btrfs: fix crash when tracepoint arguments are freed by wq callbacks

2017-01-19T19:18:02Z

commit ac0c7cf8be00f269f82964cf7b144ca3edc5dbc4 upstream. Enabling btrfs tracepoints leads to instant crash, as reported. The wq callbacks could free the memory and the tracepoints started to dereference the members to get to fs_info. The proposed fix https://marc.info/?l=linux-btrfs&m=148172436722606&w=2 removed the tracepoints but we could preserve them by passing only the required data in a safe way.

mm, compaction: rename COMPACT_PARTIAL to COMPACT_SUCCESS

2016-10-08T01:46:27Z

COMPACT_PARTIAL has historically meant that compaction returned after doing some work without fully compacting a zone. It however didn't distinguish if compaction terminated because it succeeded in creating the requested high-order page. This has changed recently and now we only return COMPACT_PARTIAL when compaction thinks it succeeded, or the high-order watermark check in compaction_suitable() passes and no compaction needs to be done. So at this point we can make the return value clearer by renaming it to COMPACT_SUCCESS. The next patch will remove some redundant tests for success where compaction just returned COMPACT_SUCCESS.

All this from Benjamin Tissoires - Report descriptor parsing would now ignore and out-of-range System controls in case of the application actually being System Control.

Pull f2fs updates from Jaegeuk Kim: "In this round, we've investigated how f2fs deals with errors given by our fault injection facility. With this, we could fix several corner cases. And, in order to improve the performance, we set inline_dentry by default and enhance the exisiting discard issue flow. In addition, we added f2fs_migrate_page for better memory management. Enhancements: - set inline_dentry by default - improve discard issue flow - add more fault injection cases in f2fs - allow block preallocation for encrypted files - introduce migrate_page callback function - avoid truncating the next direct node block at every checkpoint Bug fixes: - set page flag correctly between write_begin and write_end - missing error handling cases detected by fault injection - preallocate blocks regarding to 4KB alignement correctly - dentry and filename handling of encryption - lost xattrs of directories" * tag 'for-f2fs-4.9' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs: (69 commits) f2fs: introduce update_ckpt_flags to clean up f2fs: don't submit irrelevant page f2fs: fix to commit bio cache after flushing node pages f2fs: introduce get_checkpoint_version for cleanup f2fs: remove dead variable f2fs: remove redundant io plug f2fs: support checkpoint error injection f2fs: fix to recover old fault injection config in ->remount_fs f2fs: do fault injection initialization in default_options f2fs: remove redundant value definition f2fs: support configuring fault injection per superblock f2fs: adjust display format of segment bit f2fs: remove dirty inode pages in error path f2fs: do not unnecessarily null-terminate encrypted symlink data f2fs: handle errors during recover_orphan_inodes f2fs: avoid gc in cp_error case f2fs: should put_page for summary page f2fs: assign return value in f2fs_gc f2fs: add customized migrate_page callback f2fs: introduce cp_lock to protect updating of ckpt_flags ...
