From 219ee99d3673ded7abbc13ddd4d7847e92661e2c Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Wed, 20 Nov 2024 16:20:26 -0800 Subject: [PATCH] xfs: pretty print metadata file types in error messages Create a helper function to turn a metadata file type code into a printable string, and use this to complain about lockdep problems with rtgroup inodes. We'll use this more in the next patch. Signed-off-by: "Darrick J.
