[RFC: 2.6 patch] dump_thread() cleanup

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patch contains the following cleanups:
- create one common dump_thread() prototype in kernel.h
- dump_thread() is only used in fs/binfmt_aout.c and can therefore be
  removed on all architectures where CONFIG_BINFMT_AOUT is not
  available
