Summary: OSS emulation and nonblocking write to /dev/dsp
Description:
When you open '/dev/dsp' in nonblocking mode (O_NONBLOCK) and write too
much data to it, it seems that write operation always returns success and
pretends that all data was written. But calls to ioctl(oss_fd,
SNDCTL_DSP_GETOSPACE, &bufinfo) start returning weird information. Test
program that reproduces the bug is attached.

Just tested and reproduced the same problem on 'snd-intel8x0' (nforce2
chipset), so this is not 'snd-via82xx' specific (KT133A chipset). Please
anybody replace the summary of this bug with 'OSS emulation & nonblocking
write to /dev/dsp'.
