Subject: [219/244] [SCSI] bnx2fc: scsi_dma_unmap() not invoked on IO completions
3.0-stable review patch. If anyone has any objections, please let us know.
------------------
From: Bhanu Prakash Gollapudi <bprakash@...adcom.com>
commit b5a95fe7ef464a67fab6ff870aa740739e788f90 upstream.
Do not set io_req->sc_cmd to NULL until bnx2fc_unmap_sg_list() is called to
enable it to unmap the DMA mappings.
