Mika Penttilä 85649ed9d4 debugfs: fix error when writing negative value to atomic_t debugfs file ... JIRA: https://issues.redhat.com/browse/RHEL-1349 Upstream Status: v6.2-rc1 commit d472cf797c4e268613dbce5ec9b95d0bcae19ecb Author: Akinobu Mita <akinobu.mita@gmail.com> AuthorDate: Tue Sep 20 02:24:18 2022 +0900 Commit: Andrew Morton <akpm@linux-foundation.org> CommitDate: Wed Nov 30 16:13:16 2022 -0800 The simple attribute files do not accept a negative value since the commit 488dac0c92 ("libfs: fix error cast of negative value in simple_attr_write()"), so we have to use a 64-bit value to write a negative value for a debugfs file created by debugfs_create_atomic_t(). This restores the previous behaviour by introducing DEFINE_DEBUGFS_ATTRIBUTE_SIGNED for a signed value.
