This patch adds support for volatile writes which keep data pages in memory until f2fs_evict_inode is called by iput. For instance, we can use this feature for the sqlite database as follows. While supporting atomic writes for main database file, we can keep its journal data temporarily in the page cache by the following sequence. 1. open -> ioctl(F2FS_IOC_START_VOLATILE_WRITE); 2. writes : keep all the data in the page cache. 3. flush to the database file with atomic writes a. ioctl(F2FS_IOC_START_ATOMIC_WRITE); b. writes c. ioctl(F2FS_IOC_COMMIT_ATOMIC_WRITE); 4. close -> drop the cached data Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org> |
