Module Name:    src
Committed By:   gdt

Modified Files:
        src/sys/coda: coda_vnops.c

Log Message:
Improve conformance to vnode locking rules in coda_lookup, by doing
the unlock parent, lock child, lock parent in the ISDOTDOT case.

Clean up and rewrite comments to match more closely current reality.

Sprinkle XXX where I'm not sure the current rules are being followed.

Reviewed by wrstuden@, who agreed that this is an improvement over the
current code, with concerns about LK_RETRY and whether the ISDOTDOT
locking is done soon enough.
