From 4ca488eb45692520f745f96abc00ea4e268a87d4 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 11 Oct 2007 18:09:40 +1000 Subject: [XFS] Kill off xfs_statvfs. We were already filling the Linux struct statfs anyway, and doing this trivial task directly in xfs_fs_statfs makes the code quite a bit cleaner. While I was at it I also moved copying attributes that don't change over the lifetime of the filesystem outside the superblock lock. xfs_fs_fill_super used to get the magic number and blocksize through xfs_statvfs, but assigning them directly is a lot cleaner and will save some stack space during mount.
