Hi

I patched "LVM 1.0.5" against kernel 2.4.9-34 for RH7.2 as follows;

1.Replace files 
"KERNEL_DIR/drivers/md/lvm.c,lvm-fs.c,lvm-internal.h,lvm-snap.c;
KERNEL_DIR/include/linux/lvm.h".

with these files in lvm_1.0.5.tar.gz
"LVM/1.0.5/kernel/lvm.c,lvm-fs.c,lvm-internal.h,lvm-snap.c,lvm.h"

2.Modify lvm-snap.c as following;
Add 
"int nbhs = KIO_MAX_SECTORS;"
in the begining of both functions
"lvm_snapshot_alloc()" and "lvm_snapshot_release()"

then changes
	alloc_kiovec(1, &lv_snap->lv_iobuf),
	free_kiovec(1, &lv_snap->lv_COW_table_iobuf)
to
	alloc_kiovec_sz(1, &lv_snap->lv_iobuf, &nbhs),
	free_kiovec_sz(1, &lv_snap->lv_COW_table_iobuf, &nbhs) .

3. Apply LVM/1.0.5/PATCHES/linux-2.4.9-VFS-lock.patch like this;

cd KERNEL_DIR/
patch -p1 < LVM_DIR/LVM/1.0.5/PATCHES/linux-2.4.9-VFS-lock.patch


4. Add in KERNEL_DIR/fs/super.c
"static DECLARE_MUTEX(mount_sem);"

5. Make KERNEL

It seems to me that patch applied well and LVM worked.
