The issues which are warned about can happen as a
normal part of life when using Linux, especially
`Needs journal recovery, mounting read-only`.
This means that when using Ext4Dxe with OpenCore
it becomes necessary not to include WARN in HaltLevel,
whereas in general, to keep a clean system, one
might want to include it.
More generally this PR tries to reflect the idea that
WARNs should be to let users know of config (and
other) errors which they should really fix. Whereas
here we have a state which occurs quite commonly
and which the user can do nothing about.
I am pretty certain that (from the point of view
described above) the changes in Superblock.c are
correct. I am less certain about the changes in
Symlink.c - but all the same, if they are not errors
and the system can continue, and the user can do
nothing about it, then probably the same logic applies.
Adds a Pedro Falcato's UEFI EXT4 filesystem driver that implements the
EFI_FILE_PROTOCOL and EFI_SIMPLE_FILE_SYSTEM_PROTOCOL.
