Subject: [PATCH 0/3] fix error when writing negative value to simple attribute files

The simple attribute files do not accept a negative value since the
commit 488dac0c9237 ("libfs: fix error cast of negative value in
simple_attr_write()"), but some attribute files want to accept
a negative value.

Akinobu Mita (3):
  libfs: add DEFINE_SIMPLE_ATTRIBUTE_SIGNED for signed value
  lib/notifier-error-inject: fix error when writing -errno to debugfs
    file
  debugfs: fix error when writing negative value to atomic_t debugfs
    file
