The patch titled
for_each_possible_cpu: xfs
has been removed from the -mm tree. Its filename is
for_each_possible_cpu-xfs.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: for_each_possible_cpu: xfs
From: KAMEZAWA Hiroyuki <kamezawa.hiroyu@xxxxxxxxxxxxxx>
for_each_cpu() actually iterates across all possible CPUs. We've had mistakes
in the past where people were using for_each_cpu() where they should have been
iterating across only online or present CPUs. This is inefficient and
possibly buggy.
We're renaming for_each_cpu() to for_each_possible_cpu() to avoid this in the
future.
This patch replaces for_each_cpu with for_each_possible_cpu.
in xfs.
