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: http://wiki.freebsd.org/SOC2009AdityaSarawgi 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). http://wiki.freebsd.org/AdityaSarawgi -- Ulf Lilleengen
