Subject: [DCCP]: Fix for follows48
X-Git-Tag: v2.6.22-rc1~1128^2~242
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b16be51b5e5d75cec71b18ebc75f15a4734c62ad;p=pandora-kernel.git

[DCCP]: Fix for follows48

The follows48 relation identifies whether 48-bit sequence number
x is the direct successor of y. Currently, it does not handle cases
of the following type correctly:

	follows48(0x(prefix)10000LL, 0x(prefix)0FFFFLL)

where prefix is an arbitrary hex sequence of up to 7 digits.

This is fixed by reusing the new dccp_delta_seqno function.
