Of course, just kidding—it just takes a significant amount of time to even start reviewing when you look at complex subsystems. But no matter how complex the subsystem you're looking at is, as long as your curiosity doesn’t stop and you keep spending time on it, you’ll eventually get there.
And yeah, being good at using Git is such an important skill in a project with a long history (and being able to find and read old mailing list threads too...)

ljs@fosstodon.orgSpot on advice for any field.
For gym motivation is useless, it's all discipline, your test is on a day when you 100% hate it and want to do ANYTHING ELSE.
Music is my hobby but barely done any, because it is work really, a different kind, but if you want to get anywhere with it, you have to have the same discipline.
But I plan to apply the same gym-like discipline to that to get what I want out of it.
And of course this goes for kernel work too, obviously.

hyeyoo/me again realizes that things not documented are quickly reclaimed from memory.

@ljs protip: much easier to rack up commits if you test your commits less - you can land them faster and you get to add fix commits on top

ljs@fosstodon.orgVery happy to announce my book The Linux Memory Manager is now available to pre-order at
https://nostarch.com/linux-memory-manager
It's a comprehensive 1,300 page exploration of how memory functions in Linux that goes into great depth on the subject, and is the first book of its kind for 20 years :)
