Re: Block-level access

My access is almost purely sequential and primarily writing, so read-ahead doesn't help me. What's problematic with pread/pwrite is the lack of error channel from media errors. BSG looks very interesting. I'll look further into that today. On Thu, Sep 1, 2016 at 5:16 PM, Bart Van Assche

[PATCH] MIPS: Malta: Fix IOCU disable switch read for MIPS64

Malta boards used with CPU emulators feature a switch to disable use of an IOCU. Software has to check this switch & ignore any present IOCU if the switch is closed. The read used to do this was unsafe for 64 bit kernels, as it simply casted the address 0xbf403000 to a pointer & dereferenced it.
