Considering that the threading library for Linux uses signals to make it
work, would it be possible to change the Linux kernel to operate the way
BSD does--instead of returning EINTR, just restart the interrupted
primitive?
For example, if I'm using read(2) to read data from a file descriptor,
and a signal happens, the signal handler runs, and read(2) returns EINTR
after the system call finishes. Then I'm supposed to catch this and
re-try the system call.
I assume that this is true for _any_ system call which makes the process
block, right?
Can we _PLEASE_PLEASE_PLEASE_ not do this anymore and have the kernel do
what BSD does: re-start the interrupted call?
Please? If this is something that would be acceptable for integration
into a mainline kernel, I would do my best to help with a patch.
If I'm wrong about this, please enlighten me. Also, please cc: me off
the list, as I don't get the list directly.
Thank you for your consideration.
