Hello everyone, 1. My background I am a professional software engineer with 1.5 years of experience. For 6-7 months, I worked on creating my own Unix-like kernel from scratch for my x86-64 laptop. I wrote the device drivers for NVMe over PCIe, a local APIC timer and interrupt controller (x2APIC mode), a PS/2 keyboard, the real-time clock, and terminal output. I developed my own UEFI bootloader and worked on an interrupt handling mechanism. I implemented a physical memory manager using the free stack data structure and an ext2 file system driver. I briefly worked on my own flat file system as an experiment. I also experimented with my own 64-bit paging for a while. That's it. I know a good amount of C (I think my skill in C is between beginner-intermediate level) and I have a year of experience using it. I also did Google Summer of Code with KDE in 2018. There I used C++. 2. My question How can I begin contributing to the linux kernel? I already have one contribution but that is about fixing a checkpatch.pl warning (see [0]). Now I think I want to begin fixing a beginner bug in a subsystem like "filesystem". I am interested in filesystems. I searched a lot about this over the internet but I can't figure out what I need to do and need to learn to begin contributing again. Thanks.
