Subject: Use send_sig() instead of kill_proc() in emulated kthread support.
X-Git-Url: http://rtime.felk.cvut.cz/gitweb/lincan.git/commitdiff_plain/7c1986e7d366ac059716effeac68e5e081a081c9?hp=c1a3209a7cdb41a4a78caf3a5e0d3435deb4e43d

Use send_sig() instead of kill_proc() in emulated kthread support.

This allows to compile driver on latest 2.6.27+ kernels,
but is incorrect anyway. The local code for kernel thread
support is not more needed for recent 2.6 kernels and code
should be modified to emulate same interface for older ones.
