Subject: NFTL cleanup
Date: Thu, 17 Aug 2000 08:49:46 +0100 [thread overview]
Message-ID: <21418.966498586@cygnus.co.uk> (raw)
I've realised that we're not permitted to use a semaphore, or call any of
the MTD access functions, from the nftl_request() function.
The nftl_request() function isn't permitted to sleep.
Therefore, we want a kernel thread. The _request function should do nothing
but take requests off the kernel's queue and stick them on a private queue,
to be served by the kernel thread.
Once we do proper concurrent access to individual flash chips within the
DiskOnChip, that'll become _very_ important.
