    saner FASYNC handling on file close · 233e70f4
    Al Viro authored
    As it is, all instances of ->release() for files that have ->fasync()
    need to remember to evict file from fasync lists; forgetting that
    creates a hole and we actually have a bunch that *does* forget.
    
    So let's keep our lives simple - let __fput() check FASYNC in
    file->f_flags and call ->fasync() there if it's been set.  And lose that
    crap in ->release() instances - leaving it there is still valid, but we
    don't have to bother anymore.
