From 41fa9f863baacd32dd049daf8050d55a0c9e6f1a Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Tue, 31 Mar 2009 20:15:25 +0200 Subject: ide: decrease size of ->pc_buf field in struct ide_atapi_pc struct ide_atapi_pc is often allocated on the stack and size of ->pc_buf size is 256 bytes. However since only ide_floppy_create_read_capacity_cmd() and idetape_create_inquiry_cmd() require such size allocate buffers for these pc-s explicitely and decrease ->pc_buf size to 64 bytes.
