The patch titled Subject: lib/bitmap.c: remove unused EXPORT_SYMBOLs has been added to the -mm tree. Its filename is lib-bitmapc-remove-unused-export_symbols.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/lib-bitmapc-remove-unused-export_symbols.patch and later at http://ozlabs.org/~akpm/mmotm/broken-out/lib-bitmapc-remove-unused-export_symbols.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/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Rasmus Villemoes <linux@xxxxxxxxxxxxxxxxxx> Subject: lib/bitmap.c: remove unused EXPORT_SYMBOLs AFAICT, there have never been any callers of these functions outside mm/mempolicy.c (via their nodemask.h wrappers). In particular, no modular code has ever used them, and given their somewhat exotic semantics, I highly doubt they will ever find such a use. In any case, no need to export them currently.
