From ee2411a8db49a21bc55dc124e1b434ba194c8903 Mon Sep 17 00:00:00 2001 From: Steven Whitehouse Date: Thu, 12 Dec 2013 17:29:32 +0000 Subject: GFS2: Clean up quota slot allocation Quota slot allocation has historically used a vector of pages and a set of homegrown find/test/set/clear bit functions. Since the size of the bitmap is likely to be based on the default qc file size, thats a couple of pages at most. So we ought to be able to allocate that as a single chunk, with a vmalloc fallback, just in case of memory fragmentation. We are then able to use the kernel's own find/test/set/clear bit functions, rather than rolling our own.
