Its filename is zsmalloc-fixup-trivial-zs-size-classes-value-in-comments.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/zsmalloc-fixup-trivial-zs-size-classes-value-in-comments.patch and later at http://ozlabs.org/~akpm/mmotm/broken-out/zsmalloc-fixup-trivial-zs-size-classes-value-in-comments.patch 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/SubmitChecklist when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Weijie Yang <weijie.yang@xxxxxxxxxxx> Subject: zsmalloc: fixup trivial zs size classes value in comments According to calculation, ZS_SIZE_CLASSES value is 255 on systems with 4K page size, not 254. The old value may forget count the ZS_MIN_ALLOC_SIZE in. This patch fixes this trivial issue in the comments.
