by admin ·
With a few days delay, because of the holidays, Linus Torvalds released the Linux kernel 3.2. One of the innovations are extensions in the Ext filesystem fourth
Know how Ext4 developer Ted Ts’o was already at the LinuxCon Europe, is characterized by the feature Bigalloc guarantees that Ext 4 in many jobs do not come into swapping by Ext up with 4 instead of block sizes from 4 Kbytes to so-called cluster sizes 1 MB uses. This fall a few entries in the bitmap, making it easier to fit into memory. Since the bitmaps are also frequently called upon, they will remain in memory, which ensures low latency. The newly added extensions are not backwards compatible.
Btrfs also has undergone revisions and has among other things, the so-called scrubbing, reviewing the entire check sums become faster. With support for Qualcomm’s Hexagon Achitecture hardware side has also done something. The changelog mentions in detail the changes. The website kernelnewbies also has an understandable summary of the changes online.
