From: Gerrit Renker Date: Tue, 20 Nov 2007 23:56:37 +0000 (-0200) Subject: [DCCP]: Make PARTOPEN an autonomous state X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9b91ad2747891767c0efb4fb965c5dfed8d4f88e;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git [DCCP]: Make PARTOPEN an autonomous state This decouples PARTOPEN from TCP-specific stream-states. It thus addresses the FIXME. The code has been checked with regard to dependency on PARTOPEN and FIN_WAIT1 states (to which PARTOPEN previously was mapped): there is no difference, as PARTOPEN is always referred to directly (i.e. not via the mapping to TCP state).
