[PATCH 5/6 v2]kernel:module.c variable 'nowarn' set but not used
in [Kernel]
|
Prev: Dell PowerEdge 4200 scsi, worked in 2.6.18, not in 2.6.26 (LOW PRIORITY help request)
Next: [PATCH 6/6 v2]afs:fsclient.c Fix variable 'bp' set but not used
From: Justin P. Mattock on 19 Jun 2010 16:40 This is a resend from the original, due to the original being wrong, and having whitespace issues. The below patch marks the variable nowarn __unused to satisfy gcc 4.6.0 from giving this warning: CC kernel/module.o kernel/module.c: In function 'add_usage_links': kernel/module.c:1343:6: warning: variable 'nowarn' set but not used after doing this the warning message goes away, but checkpatch.pl gives a warning about externs should be avoided, so am not sure this is the right approach(but could be wrong).
