The patch titled
root mount failure: emit filesystems attempted
has been removed from the -mm tree. Its filename is
root-mount-failure-emit-filesystems-attempted.patch
This patch was probably dropped from -mm because
it has now been merged into a subsystem tree or
into Linus's tree, or because it was folded into
its parent patch in the -mm tree.
From: Andy Whitcroft <apw@xxxxxxxxxxxx>
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)
