From 88459642cba452630326b9cab1c651e09577d4e4 Mon Sep 17 00:00:00 2001 From: Omar Sandoval Date: Sat, 17 Sep 2016 08:38:44 -0600 Subject: blk-mq: abstract tag allocation out into sbitmap library This is a generally useful data structure, so make it available to anyone else who might want to use it. It's also a nice cleanup separating the allocation logic from the rest of the tag handling logic. The code is behind a new Kconfig option, CONFIG_SBITMAP, which is only selected by CONFIG_BLOCK for now. This should be a complete noop functionality-wise.
