vfs: fix lock inversion in drop_pagecache_sb()
Fix longstanding lock inversion in drop_pagecache_sb by dropping inode_lock
before calling __invalidate_mapping_pages(). We just have to make sure inode
won't go away from under us by keeping reference to it and putting the
reference only after we have safely resumed the scan of the inode list. A bit
tricky but not too bad...
