From 47dd674372891cf2e5cc7d0bbba3e648653a235e Mon Sep 17 00:00:00 2001 From: chandan Date: Wed, 25 Jan 2017 20:02:43 -0600 Subject: [PATCH] xfs_db: Interpret inode's di_format field as unsigned On a ppc64 big endian system, xfs_db would print the following, xfs_db> p core.magic = 0x494e core.mode = 0100600 core.version = 3 core.format = -253 This is due to fp_dinode_fmt() interpretting the di_format field as signed. This commit fixes the bug by passing BVUNSIGNED (instead of BVSIGNED) as the argument to getbitval(). With this commit applied, we now get, xfs_db> p core.magic = 0x494e core.mode = 0100600 core.version = 3 core.format = 3 (btree) Signed-off-by: Chandan Rajendra Reviewed-by: Darrick J.
