does not trigger assertions in uvm_fault, and executing files from
coda works as well.
Code very lightly reviewed by wrstuden@; scrutiny by those who
understand vnode and especially {get,put}pages would be appreciated.
After resuming execution, the thread must check to see if it
has been restarted as a result of pthread_cond_signal(). If it
has, but cannot take the wakeup (because of eg a pending Unix
signal or timeout) then try to ensure that another thread sees
it. This is necessary because there may be multiple waiters,
and at least one should take the wakeup if possible.
been nodetofh translated even if they are not valid on the sftp
server anymore, because some nfs client might still be clinging on
to the file handle we are reclaiming now.
Now, when I say support, I mean "support", due to the limitations
of the backend. File handles are valid only for one session, since
nodes can only be identified by pathnames and pathnames don't (all)
fit into the nfs file handle space. Additionally, we can't detect
if a pathname is completely replaced by another file (if it's done
via some other route that through our mount, of course). But then
again, that's an inherent problem with sshfs even without nfs.
accessors for interesting data in it. Namely, you can now get
pu->pu_privdata with puffs_getspecific(), pu->pu_pn_root with
puffs_set/getroot() and pu->pu_maxreqlen with puffs_getmaxreqlen().
were saved in the stack, but the subsequent swapcontext would return
to the earlier stack frame and never restore them. Fixes puffs
with default compiler flags on amd64.
Thanks to Mihai Chelaru for providing access to an amd64 machine
for debugging this problem.
the host share them.
Before breaking out of the loop over descriptors in gem_rint(),
DMA-resynchronize the first Rx descriptor we found that does not
belong to the host. We must avoid a cached descriptor "covering"
a descriptor in RAM, because the cached descriptor may say that
the descriptor still belongs to the NIC, when that is not true,
and the driver will hang.
XXX I believe this driver only works by luck on hosts that both
XXX have a cacheline size greater than the size of a descriptor
XXX (16 bytes) and lack DMA/cache coherency. I need to add some
XXX trickery to make sure that we don't scribble over the NIC's
XXX changes to a descriptor when we flush a cached descriptor to
XXX RAM with bus_dmamap_sync(9).
break other implementations so lookup the physical number instead of
indexing it. Choosing random numbers here is legal according to the specs,
but not a logical choice and most likely done as a wierd kind of copy
protection.
