Hi,
I ran this script tree times,
#! /bin/sh
for i in `find /sys/ -type f`
do
echo "wyświetlam $i"
sudo cat $i > /dev/null
done
First run - scheduler bug
Second run - NOHZ bug
Third - VFS bug

As explained by Christoph Lameter, ext3_alloc_inode() touches the same
cache line as init_once() so we gain nothing from using slab
constructors. The SLUB allocator will be more effective without it
(free pointer can be placed inside the free'd object), so m

Add ext4migrate utility that helps in migrating a ext3 block mapped
inode to ext4 extent mapped inode.
ext4migrate command takes the below syntax

The --display option helps in displaying the block map details for a

What does "find some dirty unallocated blocks" mean? Find a page which is
dirty and which does not have a disk mapping?
Normally the above operation would be implemented via
