From 3e2221c73cba7d33fd5706f9bc4906ffaf421478 Mon Sep 17 00:00:00 2001 From: Dave Kleikamp Date: Wed, 25 Apr 2007 09:36:20 -0500 Subject: Copy i_flags to jfs inode flags on write This mirrors Jan Kara's patches for ext3. This patch makes sure that changes made to inode->i_flags are reflected on disk for jfs. It also moves a call of jfs_set_inode_flags() to be more consistent with where jfs_get_inode_flags() is called.

The jfsIO thread should set the state before giving up the spinlock, so the waking thread will really wake it.
