This test was failing on my machine when run natively but not causing any
problems when run within qemu, and the failure was "mkdir: No space left
on device".
My understanding of the issue is that this test overflowed the temporary
disk image due to its high rate of file churn and the lfs_cleanerd not
being able to keep up. Note that this test is capped by time, not number
of operations, so this is why the problem does not show up in a slow
emulated system.
To fix this, just bump the test file system image limit a little bit.
(I tried increasing the frequency at which lfs_cleanerd does its thing,
but it wasn't enough.)
If mount_tmpfs fails, show what the stderr output of the command was instead
of failing without details.
While doing this, remove the stupidity to deal with the optional arguments
to the test_mount routine.
This is wrong. The zfs tests already use rump so they should not require
root. However, I've already spent much more time than I wanted trying to
figure out why that's the case without much luck. If you can find why,
just remove this hack.
XXX: Instead of making a copy of the libc rpc files here we should re-use the
files from libc, and use macros to provide the extra functionality needed here.

when a on-disk block/inode allocation triggers allocating a new
quota entry, the new quota entry is not in the quota2 header block,
and the allocation will later be denied, the changes to the quota block would
not be flushed to disk, leading to list corruption (detected by fsck).
builds to not hide them in the future:
(1) Don't use a pointer to a local variables if all that is done is
comparing it against NULL. The function itself works fine for that
purpose.
(2) Initialise the fail counter, giving the test a chance to work
reliably.
Adapt dholland@'s fix to ufs_rename to fix PR kern/43582. Address several
other MP locking issues discovered during the course of investigating the
same problem.
Removed extraneous vn_lock() calls on the Ifile, since the Ifile writes
are controlled by the segment lock.
Fix PR kern/45982 by deemphasizing the estimate of how much metadata
will fill the empty space on disk when the disk is nearly empty
(t_renamerace crates a lot of inode blocks on a tiny empty disk).
state of the stream. Change argument of the seek function to funopen() from
fpos_t to off_t. Make f{g,s}etpos() use the new fpos_t struct, while providing
backwards compatible entry points. Approved by releng@
