From 5e33cd0c5a299772b5ec1a493f0a77548664ae06 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Sun, 22 Feb 2015 10:21:07 -0800 Subject: [PATCH] ipmi: Remove incorrect use of seq_has_overflowed commit d6c5dc18d863 ("ipmi: Remove uses of return value of seq_printf") incorrectly changed the return value of various proc_show functions to use seq_has_overflowed(). These functions should return 0 on completion rather than 1/true on overflow. 1 is the same as #define SEQ_SKIP which would cause the output to not be emitted (skipped) instead. This is a logical defect only as the length of these outputs are all smaller than the initial allocation done by the seq filesystem.
