Subject: [PATCH] kmsg_write: don't return printk return value
X-Git-Tag: v2.6.16-rc1~775
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=cd140a5c1f456f50897af4a2e9a23d228a5fe719;p=pandora-kernel.git

[PATCH] kmsg_write: don't return printk return value

kmsg_write returns with printk, so some programs may be confused by a
successful write() with a return value different than the buffer length.

# /bin/echo something > /dev/kmsg
/bin/echo: write error: Inappropriate ioctl for device

The drawbacks is that the printk return value can no more be quickly
checked from userspace.
