From fa9b227e9019ebaeeb06224ba531a490f91144b3 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 14 Jun 2010 05:17:31 -0400 Subject: xfs: new truncate sequence Convert XFS to the new truncate sequence. We still can have errors after updating the file size in xfs_setattr, but these are real I/O errors and lead to a transaction abort and filesystem shutdown, so they are not an issue. Errors from ->write_begin and write_end can now be handled correctly because we can actually get rid of the delalloc extents while previous the buffer state was stipped in block_invalidatepage. There is still no error handling for ->direct_IO, because doing so will need some major restructuring given that we only have the iolock shared and do not hold i_mutex at all. Fortunately leaving the normally allocated blocks behind there is not a major issue and this will get cleaned up by xfs_free_eofblock later. Note: the patch is against Al's vfs.git tree as that contains the nessecary preparations. I'd prefer to get it applied there so that we can get some testing in linux-next.
