1: I can understand it, and
2: It works.
Notable externally-visible changes are that POOL_SUBPAGE now has to be a
compile-time constant, and that trying to initialise a pool whose objects are
larger than POOL_SUBPAGE automatically generates a pool that doesn't use
subpages.
NetBSD/acorn26 now boots multi-user again.
- Always look for labels in the first two sectors
- Update all existing labels, but only write new labels to netbsd mbr
partitions, and the first/second sector of disks that don't have an mbr.
Moving disks between systems still sucks bigtime!
- raw patition is either c or d, if d then c is reserved
- max partitions might be 8 or 16, nothing in the label gives the maximum
- endianness
the time pool_get() calls pool_catchup(), pp has been free'd but it is still
in the "entered" state. The chain pool_catchup() -> pool_allocator_alloc()
-> pool_reclaim() on pp fails because pp is still in the "entered" state.
Call pr_leave() before calling calling pool_catchup() to avoid this.
Thanks for the excellent analysis!
Be more flexible in what we accept as a valid LINTSTUB directive.
Don't abort on first error.
Separate LINTSTUB comments look ugly if the function/variable already
has a descriptive comment. People don't like to write ugly code.
Now one can write:
/*
* LINTSTUB: Func: type function(args)
* Some descriptive comment about the function.
*/
buffer when the passed nested buffer has no B_ERROR flag set but not all
was transfered for the nested iobuf extent.
Discussed on tech-kern and ok'd by Takashi
otherwise generate an UVM trap or will access random memory. This is due to
the dereference of vp->v_specmountpoint that is really
vp->v_specinfo->si_mountpoint. The field v_specinfo is multiplexed with
other structs in the vun union in struct vnode like struct socket.
The patch adds a sanity check for accessing the specinfo fields by only
allowing VBLK nodes to be passed. In theory also VCHR could be valid since
its also a special node though mounting is only done on VBLK so be strict.
Ok'd by yamt.
- for structure fields that are conditionally present,
make those fields always present.
- for functions which are conditionally inline, make them never inline.
- remove some other functions which are conditionally defined but
don't actually do anything anymore.
- make a lock-debugging function conditional on only LOCKDEBUG.
as discussed on tech-kern some time back.
