Major difference between between the new SCR functions and the old

affirmitive of the condition.  e.g.  if SCR is unaccessible or
presence cannot be determined for other reasons, these functions

host_eh_scheduled where needed and exports scsi_eh_wakeup() to

following discussion.

http://thread.gmane.org/gmane.linux.scsi/23853/focus=9760

In short, SCSI host is not supposed to know about exceptions unrelated
to specific device or command.  Such exceptions should be handled by
transport layer proper.  However, the distinction is not essential to
ATA and libata is planning to depart from SCSI, so, for the time
being, libata will be using SCSI EH to handle such exceptions.

Releasing the file would release the vfsmount which in turn would

fuse_put_super() tries to acquire this same semaphore, a deadlock
