The lock number in /proc/locks (first field) is implemented by a counter
(private field of struct seq_file) which is incremented at each call of
locks_show() and reset to 1 in locks_start() whatever the offset is. It
should be reset according to the actual position in the list. Because of
this, the numbering erratically restarts at 1 several times when reading a
long /proc/locks file.
Moreover, locks_show() can be called twice to print a single line thus
skipping a number. The counter should be incremented in locks_next().
And last, pos is a loff_t, which can be bigger than a pointer, so we don't
use the pointer as an integer anymore, and allocate a loff_t instead.
