Package: util-linux
Version: 2.12r-6
Severity: normal
Tags: patch
The blockdev command does not currently support the BLKFRASET and
BLKFRAGET syscalls. This functionality is needed on 2.4 kernels to allow
laptop-mode-tools to set the filesystem readahead. See laptop-mode-tools
bug #355492 for more information. A patch to achieve the desired
functionality is attached. I'll try to submit it upstream as well, because this
functionality should really be in there.
Cheers,
Bart
