g_vfs_done and error 11 (EDEADLK)

[J. Porter Clark]

Anyone know why FreeBSD would give g_vfs_done errors with EDEADLK?

The gpt/enc.eli is a GELI partition. ufs/var is not.  If I go to
the offset in ufs/var, it turns out to point to the syslog entry
corresponding to the previous line.  What's really strange is
that none of the files on either disk appear to be corrupted.

smartctl shows no errors on either drive. dding the entire drive
produces no errors.  The GELI drive is exported via samba.  The
errors are triggered when accessing the samba share from a PC.
This is not reliably repeatable.

My question is: What does error = 11 mean in this context?
