2023-02-04Kernel+SystemServer+Base: Introduce the RAMFS filesystemLiav A
This filesystem is based on the code of the long-lived TmpFS. It differs from that filesystem in one keypoint - its root inode doesn't have a sticky bit on it. Therefore, we mount it on /dev, to ensure only root can modify files on that directory. In addition to that, /tmp is mounted directly in the SystemServer main (start) code, so it's no longer specified in the fstab file. We ensure that /tmp has a sticky bit and has the value 0777 for root directory permissions, which is certainly a special case when using RAM-backed (and in general other) filesystems. Because of these 2 changes, it's no longer needed to maintain the TmpFS filesystem, hence it's removed (renamed to RAMFS), because the RAMFS represents the purpose of this filesystem in a much better way - it relies on being backed by RAM "storage", and therefore it's easy to conclude it's temporary and volatile, so its content is gone on either system shutdown or unmounting of the filesystem.

Add a note on hardcoded paths so everyone know that this is not an appropriate thing to do when writing kernel code.

2021-09-05Kernel: Make all Spinlocks use u8 for storage, remove templateBrian Gianforcaro
The default template argument is only used in one place, and it looks like it was probably just an oversight. The rest of the Kernel code all uses u8 as the type. So lets make that the default and remove the unused template argument, as there doesn't seem to be a reason to allow the size to be customizable.
