With all the euphoria about softupdates. I thought I should put out a reminder.. Soft updates is still not quite complete.. there is still a missing dependency that needs to be caught. It results in the occasional directory entry hitting the disk before the inode. This is still a lot safer than the old 'sync' code but it does indicate that people should not just 'trust it blindly'. in the light of softupdates, what 'sync()' does needs to be carefully thought about because there is room there for confusion. (I have not yet visited that code heavily) The dependency problem has been reproduced under BSDI. julian On Sat, 16 May 1998, Brian Somers wrote: > > Well, my machine's locked up again !
