  fs: Remove dcookies support (2021-01-29 10:06:46 +0530)

----------------------------------------------------------------
Remove oprofile and dcookies support

The "oprofile" user-space tools don't use the kernel OPROFILE support any more,
and haven't in a long time. User-space has been converted to the perf
interfaces.

The dcookies stuff is only used by the oprofile code. Now that oprofile's
support is getting removed from the kernel, there is no need for dcookies as
well.

Remove kernel's old oprofile and dcookies support.
