Overview
This page summarizes the process of contributing code to the ext4 kernel driver or to e2fsprogs.
e2fsprogs
- Clone the e2fsprogs git repo (git://git.kernel.org/pub/scm/fs/ext2/e2fsprogs.git)
- Make your code modifications as you see fit.
- Write some functional tests (see tests/ for examples, and use
make testnew
to generate a new test) if you're writing new code. - Run the regression suite:
make check
. - Wash, rinse, repeat until your code does what you want it to do.
- Static analysis, part 1: Run
make gcc-wall-new
to compile with all GCC warnings enabled. - Static analysis, part 2: Run
make clean; make C=1
to check your code against sparse. - Regression tests: Run
cd tests/; make test_script; ./test_script --valgrind-leakcheck
to look for memory leaks. - When writing up your patches, please follow the guidelines in https://www.kernel.org/doc/Documentation/SubmittingPatches
- 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.
