From 94c6d6d815c0295b101b45a101007fcf22c5171a Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 25 May 2009 10:08:52 +0200 Subject: [PATCH] fix raw_pread_aligned return value raw_pread_aligned currently returns the raw return value from lseek/read, which is always -1 in case of an error. But the callers higher up the stack expect it to return the negated errno just like raw_pwrite_aligned.
