From: Anton Vorontsov Date: Tue, 10 Jul 2012 00:10:40 +0000 (-0700) Subject: pstore: Introduce write_buf backend callback X-Git-Tag: v3.6-rc1~100^2~165 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=897dba027445be93f40e5caf550556ca38c48c51;p=pandora-kernel.git pstore: Introduce write_buf backend callback For function tracing we need to stop using pstore.buf directly, since in a tracing callback we can't use spinlocks, and thus we can't safely use the global buffer. With write_buf callback, backends no longer need to access pstore.buf directly, and thus we can pass any buffers (e.g. allocated on stack).
