Hello, Reading this http://web.mit.edu/tytso/www/linux/ext2intro.html I understand that ext2 preallocates 8 blocks when a writing data to a file. Ext3 uses the windows reservations method, but is that ext3 also preallocates 8 blocks when writing data ? Moreover, this page http://kernelnewbies.org/Ext4#head-b2148d2a96d22a1bd7e376e6c08e4a38d08fb157 explains that ext3 allocates one block at a time and ext4 uses multiblock allocation that is, allocates many block in a single system call. What is the difference between preallocation on ext2 (and ext3 ?) and mballoc ?
