You can do a smaller pledge via the custom pledge button if you want.
Just to be clear: This is apparently unrelated to the (not that unusual) not-yet-accepted PRs and their lkml review discussions.
From Overstreet's Patreon post:
"The company that's been funding bcachefs for the past 6 years has, unfortunately, been hit by a business downturn - they've been affected by the strikes in the media production industry. As such, I'm now having to look for new funding.
This came pretty unexpectedly, and puts us in a bit of a bind; with the addition of Hunter (who's already doing great work), I'm stretched thin, without much of a buffer."

I was concerned that without this context some might assume this is a "sponsors pulling out" type situation.
My understanding is that at some point during development of bcache, Kent realized "hmm... if I just got rid of cache eviction and cleaned this up a bit, it would make a nice light-weight CoW SSD-optimized filesystem".
My understanding is that there are very few untried ideas in bcachefs, and it's a relatively low-risk project. Having been burned by over-enthusiastic early adoption of btrfs, I'm hoping bcachefs becomes a conservative alternative for distros that don't currently use a CoW filesystem as the default filesystem. (Okay, I did use rsync to weekly mirror to ext4, so maybe "burned" is too strong a word, but I did wedge btrfs a few times by over-filling it.)
