Subject: Update delayed ref tracepoints for v3.12
X-Git-Tag: v2.11.0-rc1~38
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=fde8b34a4661d3e97db4a9a13018cdc2fd898a6e;p=lttng-modules.git

Update delayed ref tracepoints for v3.12

In v3.12 'btrfs_delayed_tree_ref' was split in 2 tracepoints and the
name was kept as an event class which did not trigger a build failure.

See upstream commit:

  commit 599c75ec3f7f3b606e8a0a684c00f12190712de8
  Author: Liu Bo <bo.li.liu@oracle.com>

    Btrfs/tracepoint: update delayed ref tracepoints

    This shows exactly how btrfs processes the delayed refs onto disks,
    which is very helpful on understanding delayed ref mechanism and
    debugging related bugs.
