[New-bugs-announce] [issue16834] ioctl mutate_flag behavior in regard to the buffer size limit

New submission from Yuval Weinbaum:
In fcntl module, the documentation states the following regarding the mutate_flag in ioctl method:
If it is false, the buffer’s mutability is ignored and behaviour is as for a read-only buffer, except that the 1024 byte limit mentioned above is avoided – so long as the buffer you pass is as least as long as what the operating system wants to put there, things should work.
However, looking at the code (fcntlmodule.c) it seems that the 1024 bytes limitation is avoided when the mutate_flag is set to True (the opposite of what is stated in the doc).
