From f392e6319a4e9a028b0c8b48f000bb01d660ad53 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Sun, 18 Dec 2011 20:00:10 +0000 Subject: xfs: replace i_pin_wait with a bit waitqueue Replace i_pin_wait, which is only used during synchronous inode flushing with a bit waitqueue. This trades off a much smaller inode against slightly slower wakeup performance, and saves 12 (32-bit) or 20 (64-bit) bytes in the XFS inode.
