LVM known problems, 07/01/98

Known problems with then LVM 0.4 alpha release.

1. With the 2.0 kernel, the lvm.c does not compile. The patch below
below fixes this.

          return -EINTR;
       }

2. When compiling the lvm.o module for SMP you need to fix the
compiler options manually (you need to add at least a -D__DMP__
in the kernel/Makefile).

3. An initial vgscan is required before pvcreate can be used for
the first time. pvcreate checks for /etc/lvmtab and /etc/lvmtab.d
which do not exist. vgscan will create an empty one.

4. The installation process as documented in INSTALL only works
with kernel versions 2.0.33, 2.1.98, 2.1.101, 2.1.102 and 2.1.105.
Separate patches of the kernel modifications are available (this 
affects the files ksyms.c and ll_rw_blk.c).
