This page summarizes the process of contributing code to the ext4 kernel driver or to e2fsprogs.
1. Clone the e2fsprogs git repo (git://git.kernel.org/pub/scm/fs/ext2/e2fsprogs.git) 1. Make your code modifications as you see fit. 1. Write some functional tests (see tests/ for examples) if you're writing new code. 1. Static analysis, part 1: Run
make gcc-wall-newto compile with all GCC warnings enabled. 1. Static analysis, part 2: Run
make clean; make C=1to check your code against sparse. 1. Regression tests: Run
cd tests/; make test_script; ./test_script --valgrind-leakcheckto look for memory leaks. 1. When writing up your patches, please follow the guidelines in https://www.kernel.org/doc/Documentation/SubmittingPatches 1. Send patches to the mailing list linux-ext4 at vger.kernel.org.
While Eric Sandeen and Ted T'so occasionally upload code snapshots to Coverity as an additional checkpoint, these steps can be performed by any developer.
