From 0a50f162af6ddc2db02c9edc5bbb823c336100a4 Mon Sep 17 00:00:00 2001 From: Brian Foster Date: Mon, 12 Oct 2015 16:02:08 +1100 Subject: xfs: add an xfs_zero_eof() tracepoint Add a tracepoint in xfs_zero_eof() to facilitate tracking and debugging EOF zeroing events. This has proven useful in the context of other direct I/O tracepoints to ensure EOF zeroing occurs within appropriate file ranges.
