From 43518812d297179ae1e432d5cd640ec168596283 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 3 Nov 2017 10:34:45 -0700 Subject: xfs: remove support for inlining data/extents into the inode fork Supporting a small bit of data inside the inode fork blows up the fork size a lot, removing the 32 bytes of inline data halves the effective size of the inode fork (and it still has a lot of unused padding left), and the performance of a single kmalloc doesn't show up compared to the size to read an inode or create one. It also simplifies the fork management code a lot. Signed-off-by: Christoph Hellwig Reviewed-by: Darrick J. Wong Signed-off-by: Darrick J.
