It worked for a single sync thread, but was not reentrant and\ntriggered infinite loops when multiple syncers came along.\n\nInstead, move inodes with dirty to a separate cap_dirty_migrating list\nwhen in the limbo export-but-no-import state, allowing us to go back to\nthe simple loop structure (which was reentrant).  This is cleaner and more\nrobust.\n\nAudited the cap_dirty users and this looks fine:\nlist_empty(\u0026ci-\u003ei_dirty_item) is still a reliable indicator of whether we\nhave dirty caps (which list we\u0027re on is irrelevant) and list_del_init()\ncalls still do the right thing.\n\nSigned-off-by: Sage Weil \u003csage@newdream.net\u003e\n"
