Hrishikesh Goyal worked on the project "Implement Ext4fs support in ReadOnly mode".
He tackled two features of an ext4fs implementation: extents and
HTree DIR read/write support. His work was committed into the NetBSD
source tree in multiple commits.
charles cui worked on adding tests for better "POSIX Test Suite
Compliance". This involved porting the Open Posix benchmark
suite to NetBSD. Many of the tests showed missing features, and
Charles worked with his mentors to improve the results. See his
summary for details.
Leonardo Taccari worked on "Split debug symbols for pkgsrc builds". He already blogged about this in much detail on this blog.
A big thank you to Google for sponsoring the students to work on
NetBSD, the students for working on the projects, and the mentors that
were helping them along!
