Does this problem also effect the 2.4 kernels?
I'm just wondering, because it sounds like a possible explination for
strange errors occurring with /dev/cobd? in coLinux, especially when used as
swap devices. Basically /dev/cobd? are simmular to ramdisks, but they
refere to files mmap'ed under Windows. They work fairly reliable, until
someone does something like "swapoff -a;swapon -a". However, coLinux is
only used with 2.4 kernels, so if the problem does not effect 2.4 kernels,
then this is not the cause.
Yes, Matt Porter previously determined that this behavior changed
sometime after 2.4.2 and on or before 2.4.17, when rd.c was modified to
perform a truncate_inode_pages() for BLKFLSBUF (could track down the
date/revision more accurately if you're interested).
