From: suzuki Date: Fri, 16 Mar 2007 21:38:25 +0000 (-0800) Subject: [PATCH] fix rescan_partitions to return errors properly X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b74a2f0913694556a027795d2954d30523fac4c5;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git [PATCH] fix rescan_partitions to return errors properly The only error code which comes from the partition checkers is -1, when they finds an EIO. As per the discussion, ENOMEM values were ignored, as they might scare the users. So, with the current code, we end up returning -1 and not EIO for the ioctl() calls. Which doesn't give any clue to the user of what went wrong.
