Subject: [merged] printk-rename-struct-log-to-struct-printk_log.patch removed from -mm tree To: joe@xxxxxxxxxxx,ming.lei@xxxxxxxxxxxxx,samuel.thibault@xxxxxxxxxxxx,mm-commits@xxxxxxxxxxxxxxx From: akpm@xxxxxxxxxxxxxxxxxxxx Date: Mon, 05 Aug 2013 12:06:03 -0700 The patch titled Subject: printk: rename struct log to struct printk_log has been removed from the -mm tree. Its filename was printk-rename-struct-log-to-struct-printk_log.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Joe Perches <joe@xxxxxxxxxxx> Subject: printk: rename struct log to struct printk_log Rename the struct to enable moving portions of printk.c to separate files. The rename changes output of /proc/vmcoreinfo.
