[HEADSUP] Google SoC work on ext2fs to be committed

[Ulf Lilleengen]

Hello,

In a few days, I will commit the ext2fs improvements done by Aditya Sarawgi 
during and after Google Summer of Code to CURRENT. Some quick notes:

- BSD licensed block and inode allocation policies for ext2fs. This involves the  use FFS1 style block and inode allocation for ext2fs. Preallocation was
  removed since it was GPL'd.
- Orlov Block Allocator for ext2fs. (Aditya can perhaps provide some details). 
- Some PR fixes and older bugs.
- Make ext2fs MPSAFE by introducing locks to per-mount datastructures.

More information along with nice shiny graphs can be found here:

and, of course, the code:
http://gitorious.org/freebsd-ext2fs/freebsd-ext2fs

As the work on support MP-safe operation may cause race conditions not
discovered yet, it is important to report on these issues as they are
encountered. Issues with the new implementation may be adressed to Aditya
(CCed).
