I believe that now you can detatch wdc/aic pcmcia card on most
The restriction (I know or I can imagine) is:
* the child device should be one of atapibus/scsibus/sd/cd/wd. if you
are using other devices, for example if you have st or uk, you lose.
* if scsictl/atactl is running, you may lose (as far as reading the
code. I should check this).
* of course if the deivce is opened with read/write and the card is
removed without closing it, you may lose.
* getdents(2) doesn't retun failiure while it should be even if under
lying deivce is revoked. some block device I/O doesn't return
failure or it hangs if I/O is active.
anyway, if you are digital camera user and you have compact flash card
and so on, this might help you.
