NeilBrown 7cff4b1836 kernfs: handle poll correctly on 'direct_read' files. ... Kernfs supports two styles of read: direct_read and seqfile_read. The latter supports 'poll' correctly thanks to the update of '->event' in kernfs_seq_show. The former does not as '->event' is never updated on a read. So add an appropriate update in kernfs_file_direct_read(). This was noticed because some 'md' sysfs attributes were recently changed to use direct reads.
