The mm-new branch of mm.git is not included in linux-next 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 various branches at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there most days ------------------------------------------------------ From: Sergey Senozhatsky Subject: zram: use GFP_KERNEL for post-processing slot allocation Date: Thu, 5 Mar 2026 11:16:03 +0900 Post-processing slot allocation used to be performed under slot bit-lock, so gfp was restricted, then we switched to a sleepable slot lock but gpf still remained restricted. Drop that restriction and use GFP_KERNEL instead.
