Subject: [PATCH] _proc_do_string(): fix short reads
X-Git-Tag: v2.6.21-rc1~274^2~247
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8d06087714b78e8921bd30b5c64202fe80c47339;p=pandora-kernel.git

[PATCH] _proc_do_string(): fix short reads

If you try to read things like /proc/sys/kernel/osrelease with single-byte
reads, you get just one byte and then EOF.  This is because _proc_do_string()
assumes that the caller is read()ing into a buffer which is large enough to
fit the whole string in a single hit.

Fix.
