nilfs2: fix missed-sync issue for do_sync_mapping_range()
Chris Mason pointed out that there is a missed sync issue in nilfs_writepages(): On Wed, 17 Dec 2008 21:52:55 -0500, Chris Mason wrote: > It looks like nilfs_writepage ignores WB_SYNC_NONE, which is used by > do_sync_mapping_range(). where WB_SYNC_NONE in do_sync_mapping_range() was replaced with WB_SYNC_ALL by Nick's patch (commit: ee53a891f47444c53318b98dac947ede963db400). This fixes the problem by letting nilfs_writepages() write out the log of file data within the range if sync_mode is WB_SYNC_ALL. This involves removal of nilfs_file_aio_write() which was previously needed to ensure O_SYNC sync writes.
