The patch titled Subject: Documentation: update the Squashfs filesystem documentation has been added to the -mm mm-nonmm-unstable branch. Its filename is documentation-update-the-squashfs-filesystem-documentation.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/documentation-update-the-squashfs-filesystem-documentation.patch This patch will later appear in the mm-nonmm-unstable branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next via the mm-everything branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there every 2-3 working days ------------------------------------------------------ From: Phillip Lougher <phillip@xxxxxxxxxxxxxxx> Subject: Documentation: update the Squashfs filesystem documentation Date: Sun, 29 Dec 2024 23:37:51 +0000 This patch updates the following which are out of date. - Zstd has been added to the compression algorithms supported. - The filesystem mailing list (for the kernel code) is changed to linux-fsdevel rather than the now very little used Sourceforge mailing list. - The Squashfs website has been changed to the Squashfs-tools github repository. - The fact that Squashfs-tools is likely packaged by the linux distribution is mentioned.
