Chris Wilson ca8d782205 drm/i915: Report -EFAULT before pwrite fast path into shmemfs ... When pwriting into shmemfs, the fast path pagecache_write does not notice when it is writing to beyond the end of the truncated shmemfs inode. Report -EFAULT directly when we try to use pwrite into the !I915_MADV_WILLNEED object. Fixes: 7c55e2c577 ("drm/i915: Use pagecache write to prepopulate shmemfs from pwrite-ioctl") Testcase: igt/gem_madvise/dontneed-before-pwrite Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Matthew Auld <matthew.william.auld@gmail.com> Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: Mika Kuoppala <mika.kuoppala@linux.intel.com> Reviewed-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20171016202732.25459-1-chris@chris-wilson.co.uk (cherry picked from commit a6d65e451c) Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>		2017-10-18 08:11:35 -07:00
