| 2024-05-19 | kernel: sched: Align 'tdq_lock' on cache line size | Ian Moffett | |
| The lock should be aligned on a cache line boundary so it isn't in a cache line with other data. This is important for 'tdq_lock' as it is used by every processor which constantly acquires and releases it. This alignment can reduce how violently cache lines bounce between processor local caches.

| 2024-03-25 | kernel: filedesc: Return status in fd_alloc() | Ian Moffett | |
| It is better for fd_alloc() to return the status and have one of the arguments point to an output than have fd_alloc() return the allocated file descriptor just like that. Signed-off-by: Ian Moffett <ian@osmora.org> | |||
