    [$] Tracepoints for the VFS?

    Fri, 18 Apr 2025 13:55:46 +0000

    Description:
    Adding tracepoints to some kernel subsystems has been controversialor disalloweddue to concerns about the user-space
    ABI that they might create. The virtual filesystem (VFS) layer has
    long been one of the subsystems that has not allowed any tracepoints, but
    that may be changing. At the 2025 Linux Storage, Filesystem, Memory
    Management, and BPF Summit (LSFMM+BPF), Ted Ts'o led a discussion about
    whether the ABI concerns are outweighed by the utility of tracepoints for
    the VFS.
