The primary repo is hosted at kernel.org. See this discussion from Jan 31, 2017 for further details.
Some patches (e.g., those taken from pull requests) may only exist on GitHub for some time. Please cross-reference both repositories.
Git status:
This is the squashfs.sourceforge.net CVS repository imported into this new git repository. All new development will be under git.
Primary development occurs at kernel.org. This GitHub repository was created as a temporary host while kernel.org was offline.
Squashfs-tools: The new Squashfs 4.3 release (2014/05/05).
kernel: obsolete, the kernel code is now in mainline at www.kernel.org.
All Squashfs kernel development trees are stored on kernel.org, under git.kernel.org:/linux/kernel/git/pkl/...
kernel-2.4: prehistoric, not updated since the 3.1 release. If you still need Squashfs support in the 2.4 kernel then use the squashfs 3.1 release. This is the last release that supported 2.4 kernels.
The kernel and kernel-2.4 directories (imported from CVS) are not really relevant anymore, but are here temporarily while I decide where to put them (I don't want to delete them and have all the pre-mainlining kernel commit history disappear from public repositories).
