From 78c377d1b5e7ef15c8c307c2aa2511602a0829c3 Mon Sep 17 00:00:00 2001 From: David Rientjes Date: Wed, 12 Jan 2011 16:59:55 -0800 Subject: [PATCH] flex_array: export symbols to modules Alex said: I want to use flex_array to store a sparse array of ATM cell re-assembly buffers for my ATM over Ethernet driver. Using the per-vcc user_back structure causes problems when stacked with things like br2684. Add EXPORT_SYMBOL() for all publically accessible flex array functions and move to obj-y so that modules may use this library.
