From 7af1443a9d319132087e1e9a3984b94c6998835c Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Wed, 19 Sep 2007 14:38:12 +1000 Subject: [POWERPC] spufs: Handle errors in SPU coredump code, and support coredump to a pipe Rework spufs_coredump_extra_notes_write() to check for and return errors. If we're coredumping to a pipe we can't trust file->f_pos, we need to maintain the foffset value passed to us. The cleanest way to do this is to have the low level write routine increment foffset when we've successfully written.
