Andreas Kling	19d3f8cab7	Kernel+LibC: Turn errno codes into a strongly typed enum ... ..and allow implicit creation of KResult and KResultOr from ErrnoCode. This means that kernel functions that return those types can finally do "return EINVAL;" and it will just work. There's a handful of functions that still deal with signed integers that should be converted to return KResults.	2021-01-20 23:20:02 +01:00
Andreas Kling	64b0d89335	Kernel: Make Process::allocate_region*() return KResultOr<Region*> ... This allows region allocation to return specific errors and we don't have to assume every failure is an ENOMEM.	2021-01-15 19:10:30 +01:00
Andreas Kling	fb4993f067	Kernel: Add anonymous files, created with sys$anon_create() ... This patch adds a new AnonymousFile class which is a File backed by an AnonymousVMObject that can only be mmap'ed and nothing else, really. I'm hoping that this can become a replacement for shbufs. :^)	2021-01-15 13:56:47 +01:00
