From: Christoph Hellwig Date: Sun, 18 Sep 2011 20:41:05 +0000 (+0000) Subject: xfs: pass bmalloca to xfs_bmap_add_extent_hole_real X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c6534249851d062113ab4d8d226be8dba8ecb92e;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git xfs: pass bmalloca to xfs_bmap_add_extent_hole_real All the parameters passed to xfs_bmap_add_extent_hole_real() are in the xfs_bmalloca structure now. Just pass the bmalloca parameter to the function instead of 8 separate parameters.
