From fcdef39c03c5beb2a7bcb627addb0b259b9c5164 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Wed, 14 Jul 2021 14:47:19 -0400 Subject: btrfs: enable a tracepoint when we fail tickets When debugging early enospc problems it was useful to have a tracepoint where we failed all tickets so I could check the state of the enospc counters at failure time to validate my fixes. This adds the tracpoint so you can easily get that information.
