Linux kernel source tree

Sqlite user Background GC - move_data_block : move page #1 - f2fs_is_atomic_file - f2fs_ioc_start_atomic_write - f2fs_ioc_commit_atomic_write - commit_inmem_pages : commit page #1 & set node #2 dirty - f2fs_submit_page_write - f2fs_update_data_blkaddr - set_page_dirty : set node #2 dirty - f2fs_do_sync_file - fsync_node_pages : commit node #1 & node #2, then sudden power-cut In a race case, we may check FI_ATOMIC_FILE flag before starting atomic write flow, then we will commit meta data before data with reversed order, after a sudden pow-cut, database transaction will be inconsistent. So we'd better to exclude gc/atomic_write to each other by using lock instead of flag checking. Signed-off-by: Chao Yu <yuchao0@huawei.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org> |

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
