Andreas Kling	a02c945ef2	Kernel: DoubleBuffer can return early if read/write is called with !size.	2019-03-20 02:12:40 +01:00
Andreas Kling	beda478821	Kernel: Make syscalls that take a buffer size use ssize_t instead of size_t. ... Dealing with the unsigned overflow propagation here just seems unreasonably error prone. Let's limit ourselves to 2GB buffer sizes instead.	2019-02-25 21:21:12 +01:00
Andreas Kling	9c51d9dfcd	Catch anyone trying to use a DoubleBuffer with interrupts disabled.	2019-01-16 01:58:11 +01:00
Andreas Kling	52c004eb53	Add internal locking to DoubleBuffer.	2019-01-15 21:43:38 +01:00
Andreas Kling	3ac977f50b	Paper over a race in DoubleBuffer. ... I'm still somewhat okay throwing InterruptDisabler at races as they screw me. Eventually I'm gonna have to devise a different strategy though.	2019-01-12 23:23:35 +01:00
Andreas Kling	ec1c487dcd	Yet another pass of style fixes.	2018-12-21 02:10:45 +01:00
Andreas Kling	bbfae19238	Move DoubleBuffer to its own files.	2018-12-03 01:51:44 +01:00
