From 1010ed132727bbf486ac28fd149ccfb0ef5cd2ab Mon Sep 17 00:00:00 2001 From: "Cohen David.A" Date: Mon, 11 May 2009 11:00:20 -0300 Subject: V4L/DVB (11840): change kmalloc to vmalloc for sglist allocation in videobuf_dma_map/unmap Change kmalloc()/kfree() to vmalloc()/vfree() for sglist allocation during videobuf_dma_map() and videobuf_dma_unmap() High resolution sensors might require too many contiguous pages to be allocated for sglist by kmalloc() during videobuf_dma_map() (i.e. 256Kib for 8MP sensor). In such situations, kmalloc() could face some problem to find the required free memory. vmalloc() is a safer solution instead, as the allocated memory does not need to be contiguous.
