The patch titled Subject: drivers/base/memory.c: clean up relics in function parameters has been added to the -mm tree. Its filename is drivers-base-memoryc-clean-up-relicts-in-function-parameters.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/drivers-base-memoryc-clean-up-relicts-in-function-parameters.patch and later at http://ozlabs.org/~akpm/mmotm/broken-out/drivers-base-memoryc-clean-up-relicts-in-function-parameters.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: Baoquan He <bhe@xxxxxxxxxx> Subject: drivers/base/memory.c: clean up relics in function parameters The input parameter 'phys_index' of memory_block_action() is actually the section number, but not the phys_index of memory_block. This is a relic from the past when one memory block could only contain one section. Rename it to start_section_nr. And also in remove_memory_section(), the 'node_id' and 'phys_device' arguments are not used by anyone. Remove them.
