[PATCH] root mount failure: emit filesystems attempted
When we fail to mount from a valid root device list out the filesystems we have tried to mount it with. This gives the user vital diagnostics as to what is missing from their kernel. For example in the fragment below the kernel does not have CRAMFS compiled into the kernel and yet appears to recognise it at the RAMDISK detect stage. Later the mount fails as we don't have the filesystem. RAMDISK: cramfs filesystem found at block 0 RAMDISK: Loading 1604KiB [1 disk] into ram disk... done. XFS: bad magic number XFS: SB validate failed No filesystem could mount root, tried: reiserfs ext3 ext2 msdos vfat iso9660 jfs xfs Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(8,1) Signed-off-by: Andy Whitcroft <apw@shadowen.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
