- Make constants static: Shrinks code and data size.
- Avoid overflow in limit calculation.
- Use uint8_t instead of u_char to match types
While here:
- Remove unnecessary casts
- s/u_int8_t/uint8_t/g
contiguous block for future fragment expansion doesn't need to
UFS_WAPBL_REGISTER_DEALLOCATION() or ffs_blkfree(); the free blocks
are now immediatelly available for use by the expanding file in further i/o
primary driver is safe removal of the deallocation registration and
hence failure point, but this also fixes degenerate case for wapbl,
and similar also for discard - if the file would be actually expanded
before wapbl commit, or before discard queue would be processed,
the filesystem would not yet see the contiguous free blocks, and
would be forced to allocate another fragment elsewhere
and PCI_IOC_DRVNAMEONBUS. the new ones also take a (autoconf) PCI bus
number, which allows lookups for any device on any pci bus node. use this
in pcictl which current reports the wrong values sometimes.
up next: use these in libpciaccess.
- add missing membar_store_store ("membar_producer") when setting a
new ldt;
- use UVM_KMF_WAITVA when allocating space for a new ldt instead of
crashing if uvm_km_alloc fails;
- if uvm_km_alloc fails in pmap_fork, bail instead of crashing;
- clarify what else is going on in pmap_fork;
- don't uvm_km_free while holding a mutex.
Also make the tracefile customizable. Unfortunately we can't merge any of
the hash changes because they have a different on-disk format. That does not
matter really because we've fixed most of the problems...
Don't consider an EP11_STAT_SETUP as an error as it's not valid for
host operation.
Should fix kern/51500: axe(4) at slhci(4) does not attach, but there are
more problems with axe(4)
The PROT_REQUIRE flag in should be set for data frames above a certain
length, but we were setting it for !data frames above a certain length,
which makes no sense at all.
