From dffe9d8da715bed4d395883add90a2d150d85729 Mon Sep 17 00:00:00 2001 From: Theodore Ts'o Date: Sat, 10 Nov 2012 22:20:05 -0500 Subject: [PATCH] ext4: do not use ext4_error() when there is no space in dir leaf for csum If there is no space for a checksum in a directory leaf node, previously we would use EXT4_ERROR_INODE() which would mark the file system as inconsistent. While it would be nice to use e2fsck -D, it certainly isn't required, so just print a warning using ext4_warning(). Signed-off-by: "Theodore Ts'o" Cc: "Darrick J.
