It would be nice to add a little more in this commit message about
"finally dropped with Linux kernel 3.14", and, if possible some
reference to documentation/URL that discusses dropping of the suport.
The only relevant piece that I found in the 3.14 change log was:
[[

parisc: Make EWOULDBLOCK be equal to EAGAIN on parisc
On Linux, only parisc uses a different value for EWOULDBLOCK which
causes a lot of troubles for applications not checking for both values.
Since the hpux compat is long dead, make EWOULDBLOCK behave the same as
all other architectures.

Is there more?
Thanks,
Michael
