nilfs2: use unlocked_ioctl

2009-04-07T15:31:19Z

Pekka Enberg suggested converting ->ioctl operations to use ->unlocked_ioctl to avoid BKL. The conversion was verified to be safe, so I will take it on this occasion. Cc: Pekka Enberg Signed-off-by: Ryusuke Konishi Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

nilfs2: remove compat ioctl code

2009-04-07T15:31:18Z

This removes compat code from the nilfs ioctls and applies the same function for both .ioctl and .compat_ioctl file operations. Signed-off-by: Ryusuke Konishi Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

nilfs2: fix missed-sync issue for do_sync_mapping_range()

2009-04-07T15:31:15Z

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.

nilfs2: segment constructor

2009-04-07T15:31:15Z

This adds the segment constructor (also called log writer). The segment constructor collects dirty buffers for every dirty inode, makes summaries of the buffers, assigns disk block addresses to the buffers, and then submits BIOs for the buffers.
