for the disklabel if the given device fails with EBUSY. Also make disklabel
errors non fatal (just fall back to ffs as per pre-autofilesystem behaviour)
Based on further discussion with Launey Thomas <ljt@alum.mit.edu>
it and free it as appropriate. Activate p2's new address space once
it references p1's.
- uvm_fork(): Make sure the child's vmspace is NULL before calling
uvmspace_share() (the child doens't have one already in this case).
These changes do not change the behavior for the current use of
uvmspace_share() (vfork(2)), but make it possible for an already
running process (such as a kernel thread) to properly attach to
another process's address space.
to the contents of the hint in the map, and the hint saved in the
map only if the two values match. When an unconditional save is
required, the "check" value passed should be map->hint (and the
compiler will optimize the test away). When deleting a map entry,
the new SAVE_HINT() will only change the hint if the entry being
deleted was the hint value (thus preserving any meaningful hint
that may have been there previously, rather than stomping on it).
- Add a missing hint update when deleting the map entry in
uvm_map_entry_unlink(). This is the fix for kern/11125, from
ITOH Yasufumi <itohy@netbsd.org>.
TULIPF_BLE /* data is big endian */
TULIPF_DBO /* descriptor is big endian */
These setting is required for Big-endian bus front-end (such as APbus for
newsmips) to work with tulip. Also,
sc_maxburst
member is added to the tulip_softc to limit the maximum burst length.
This member defaults to zero which means no restriction for burst length.
"target" filesystem, i.e. a filesystem that will probably be
mounted on /mnt during install/upgrade, but will be / when
the system is booted. Needed to deal with absolute symbolic links.
This function is (unfortunately) a verbatim copy of realpath() from libc,
with prefix handling added.
- define string `A' to contain the arch name (defaults to the port
name)
- define registers \*A and _\*A if
- deprecate _FOR_RELEASE, and just use FOR_RELEASE
code for backward copy to make overlap copy faster. This happens in
some SW like sleepycat db. Use temp labels in order to not confused
the profiling tools.
pmap_enter() cannot allocate the segmap return failure if PMAP_CANFAIL
instead of sleeping. Otherwise panic. Both alpha and i386 do this. Do
not pmap_enter_pv() until after this is done so the data structures are
not partially allocated. This should prevent pmap_page_protect() from
getting stuck when called from pagedaemon.
