A discussion of extensions to the statx()
system call comes up frequently at the Linux Storage,
Filesystem, Memory Management, and BPF Summit; this year’s edition was
no exception. Kent Overstreet led the first filesystem-only session at the
summit on querying information about filesystems that have subvolumes and
snapshots. While it was billed as a discussion on statx()
additions, it ranged more widely over new APIs needed for modern filesystems.
