Description:
VFS maintainer Christian Brauner led a discussion about the possibility of selectively dropping the contents of the page cache for a filesystem in a session at the
2024 Linux Storage,
Filesystem, Memory Management, and BPF Summit . As he described in his topic proposal , the use case that started him down this path comes from
GNOME, which wants to be able to safely suspend access to an encrypted home directory. While it is known to kernel
developers, it is surprising to others that reads from encrypted
filesystems that have been suspended will succeed if the data to be read
still exists in the
page cache.
