Subject: page_migration question

Hello,

I read Documentation/vm/page_migration but couldn't find the information I'm 
looking for.  Specifically, what locks am I supposed to hold/not hold while 
calling migrate_prep() and migrate_pages()?  Currently migrate_prep() seems to 
deadlock for reasons beyond me.  Any help appreciated.
