[$] FUSE folio conversion confusion
Kernel developers have been working to convert various internal interfaces to
use
<a href="https://lwn.net/Articles/849538/"; rel="nofollow">
folios</a>; while this process has been progressing, there is still the
occasional regression introduced by the change. In December 2024, it was
discovered that installing a
<a href="https://flatpak.org/"; rel="nofollow">
Flatpak</a> application could trigger a filesystem bug in
the kernel that would cause the software to read incorrect data from the disk.
The problem was quickly fixed — only for an another problem caused by the folio
rewrite to pop up in the same kernel subsystem. This was discovered by an Arch
Linux user, who noticed that selecting files in a Flatpak application was
causing kernel crashes. Now both bugs are fixed, but there may be more bugs to find.
