* [PATCH] update filesystems for new delete_inode behaviorMark Fasheh2005-09-09
| | | | | | | | | | | | | | Update the file systems in fs/ implementing a delete_inode() callback to call truncate_inode_pages(). One implementation note: In developing this patch I put the calls to truncate_inode_pages() at the very top of those filesystems delete_inode() callbacks in order to retain the previous behavior. I'm guessing that some of those could probably be optimized.

* [PATCH] move truncate_inode_pages() into ->delete_inode()Mark Fasheh2005-09-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow file systems supporting ->delete_inode() to call truncate_inode_pages() on their own. OCFS2 wants this so it can query the cluster before making a final decision on whether to wipe an inode from disk or not. In some corner cases an inode marked on the local node via voting may not actually get orphaned. A good example is node death before the transaction moving the inode to the orphan dir commits to the journal. Without this patch, the truncate_inode_pages() call in generic_delete_inode() would discard valid data for such inodes. During earlier discussion in the 2.6.13 merge plan thread, Christoph Hellwig indicated that other file systems might also find this useful. IMHO, the best solution would be to just allow ->drop_inode() to do the cluster query but it seems that would require a substantial reworking of that section of the code. Assuming it is safe to call write_inode_now() in ocfs2_delete_inode() for those inodes which won't actually get wiped, this solution should get us by for now. Trivial testing of this patch (and a related OCFS2 update) has shown this to avoid the corruption I'm seeing.

|/ | | | | | | | | | | | | | | - Support journals ($LogFile) which have been modified by chkdsk. This means users can boot into Windows after we marked the volume dirty. The Windows boot will run chkdsk and then reboot. The user can then immediately boot into Linux rather than having to do a full Windows boot first before rebooting into Linux and we will recognize such a journal and empty it as it is clean by definition. - Support journals ($LogFile) with only one restart page as well as journals with two different restart pages. We sanity check both and either use the only sane one or the more recent one of the two in the case that both are valid. Signed-off-by: Anton Altaparmakov <aia21@cantab.net>

This can be used by the dm hw_handlers, old sg_scsi_ioctl, and one day scsi special requests so all requests comming into scsi will have bios. All requests having bios should allow scsi to use scatter lists for all IO and allow it to use block layer functions. Signed-off-by: Jens Axboe <axboe@suse.de>
