Message-Id: <1334579134-19885-5-git-send-email-jack@suse.cz> Date: Mon, 16 Apr 2012 14:25:34 +0200 From: Jan Kara <jack@...e.cz> To: Ted Tso <tytso@....edu> Cc: linux-ext4@...r.kernel.org, Jan Kara <jack@...e.cz> Subject: [PATCH 4/4] ext4: Print error when argument of inode_readahead_blk is invalid If argument of inode_readahead_blk is too big, we just bail out without printing any error. Fix this since it could confuse users.
