Filipe Manana 3d770d44dd btrfs: avoid monopolizing a core when activating a swap file 
commit 2c8507c63f upstream.

During swap activation we iterate over the extents of a file and we can
have many thousands of them, so we can end up in a busy loop monopolizing
a core. Avoid this by doing a voluntary reschedule after processing each
extent.
