__VM_PMAP_HACK is defined (for temporary compatibility).
The __VM_PMAP_HACK code should be removed after all the
ports that define it have removed all vm_pmap references.
* prototype it before it is used (several ports compile with
-Wstrict-prototypes -Wmissing-prototypes), so this is _necessary_.
* conform to C syntax (yes, that's right, it wouldn't parse).
* make error check less error-prone, + style fixups.
- Run mountroot hooks before we attempt to mount the root device, and
destroy mountroot hooks after the root file system has been sucessfully
mounted.
- Don't panic if we can't mount root. Instead, set RB_ASKNAME and
call setroot(), which will prompt the operator for the root device
and file system type.
the client and server/shared data initialization into separate functions,
and calling the server/shared initialization directly from main().
Problem noted in PR #1308 (Kenneth Stailey) and PR #1780 (Chris Demetriou).
Fix suggested in PR #1780 by Chris Demetriou, and munged a bit by me,
and OK'd by Frank van der Linden <fvdl@netbsd.org>.
- New metrics handling. Metrics are now kept in the new
`struct disk'. Busy time is now stored as a timeval, and
transfer count in bytes.
- Storage for disklabels is now dynamically allocated, so that
the size of the disk structure is not machine-dependent.
- Several new functions for attaching and detaching disks, and
handling metrics calculation.
Old-style instrumentation is still supported in drivers that did it before.
However, old-style instrumentation is being deprecated, and will go away
once the userland utilities are updated for the new framework.
For usage and architectural details, see the forthcoming disk(9) manual
page.
