I think you're better off fixing this problem like I did for the allocation side, that is: - remove the xfs_ilock and xfs_trans_ijoin (or probably still xfs_trans_iget in your version) from xfs_rtfree_extent, and instead add asserts that the inode is locked and has an inode_item attach to it. - in xfs_bunmapi if we are dealing with an inode with the rt flag bump the reference count on the inode there and attach it to the transaction before calling into xfs_bmap_del_extent, similar to what we do in xfs_bmap_rtalloc. _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
