When many threads are trying to add or delete inode to or from

This patch changes the s_inodes field to become a per-cpu list with

This driver has two issues. First, it tries to fiddle with the hot
plugged CPU's MSR on the UP_PREPARE event, at a time when the CPU is
not yet online. Second, the driver sets the "boost-disable" bit for a
CPU when going down, but does not clear the bit again if the CPU comes
up again due to DOWN

Stephen,
thanks a lot for addressing that conflict.
