Re: umount/ls panic

[Matthew Dillon <dillon@xxxxxxxxxxxxxxxxxxxx>]

:What about the following patch?
:
:It fixes the assertion failure for the various cases listed in this
:thread.  When running ls from an unmounted /proc, cache_resolve()
:complains but I reckon this is expected:
:
:EXDEV case 1 0xcaba70c8
:EXDEV case 1 0xcaba70c8
:EXDEV case 1 0xcaba70c8
:ls: .: cross-device link

    Yes, the patch looks pretty good.  I'll test it a bit today and
    check out the error case, then commit it.
