From 30f2f0eb4bd2c43d10a8b0d872c6e5ad8f31c9a0 Mon Sep 17 00:00:00 2001 From: Kay Sievers Date: Tue, 6 May 2008 22:31:33 +0200 Subject: block: do_mounts - accept root= Some devices, like md, may create partitions only at first access, so allow root= to be set to a valid non-existant partition of an existing disk. This applies only to non-initramfs root mounting. This fixes a regression from 2.6.24 which did allow this to happen and broke some users machines :( Acked-by: Neil Brown Tested-by: Joao Luis Meloni Assirati Cc: stable Signed-off-by: Kay Sievers Signed-off-by: Greg Kroah-Hartman --- include/linux/genhd.h | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'include/linux') diff --git a/include/linux/genhd.h b/include/linux/genhd.h index e9874e7fcdf..ae7aec3cabe 100644 --- a/include/linux/genhd.h +++ b/include/linux/genhd.h @@ -525,7 +525,7 @@ struct unixware_disklabel { #define ADDPART_FLAG_RAID 1 #define ADDPART_FLAG_WHOLEDISK 2 -extern dev_t blk_lookup_devt(const char *name); +extern dev_t blk_lookup_devt(const char *name, int part); extern char *disk_name (struct gendisk *hd, int part, char *buf); extern int rescan_partitions(struct gendisk *disk, struct block_device *bdev); @@ -553,7 +553,7 @@ static inline struct block_device *bdget_disk(struct gendisk *disk, int index) static inline void printk_all_partitions(void) { } -static inline dev_t blk_lookup_devt(const char *name) +static inline dev_t blk_lookup_devt(const char *name, int part) { dev_t devt = MKDEV(0, 0); return devt; -- cgit v1.2.3
