This patch will fix the "freebsd can't read files > 1 chunk" problem. It
will almost certainly not fix the "cache files get the bootloader written
into them" problem, but there is a miniscule chance:
"cleanup osi_sleep.c to remove some additional races. this patches
removes AFS_GLOBAL_SUNLOCK and just uses that case to handle both
smp and non smp cases. osi_TimedSleep always sleeps atleast 1 hz.
(it also always sleeps interruptibly -- you might get some extra
loops but this is better than the load average running away)
sleep_on's are replaced with the more appropriate add_waitq/schedule
sequence. getevent is called after addevent since there is no
danger of GLOCK dropping. getevent/addevent isnt re-merged since
osi_Wakeup doesnt create entries in the event table."

the rest of the patch
I'm told that after we introduce ptserver nested groups we can expect to
see periodic pauses in ubik operations, and this fixes the problem. if it
happens, we can start with the UBIK_PAUSE code and go from there
"the attached patch 'fixes', in my opinion, in osi_alloc. objects <=
AFS_SMALLOCSIZ are alloced with kmalloc, other vmalloc. if kmalloc
fails it doesnt fail over to vmalloc. TASK_RUNNING is set after
schedule. it doesnt drop the GLOCK. i moved the allocator init
later so that it doesnt need to toggle the semaphore just before
going to linux_alloc."
#define CONFIG_SMP 1
instead of:
#define CONFIG_SMP
to fix recent Redhat kernel which used #if CONFIG_SMP instead of
#ifdef CONFIG_SMP in some kernel headers.
lha@stacken.kth.se complained that we sometimes printed garbage, so i took
the opportunity to both fix it and update ours to support the options
the arla vos listaddrs does
given that we don't bother to do anything to return value, we can ack
the fssync op earlier and not tie up the volserver unnecessarily
found due to comments from brent.johnson@jpl.nasa.gov
based on comments and suggestion from Srikanth Vishwanathan <vsrikanth@in.ibm.com>
avoid deadlock. send back variable length list. allocate what we need to, and
be care to clean up after ourselves if there's an error. whether this
should be variable length is arguable but it's pretty clear no one was using
this before.
