+This was due to a local struct resource variable in acpi_get_pmu_hw_inf().
+A pointer to that struct makes it's way to __devm_ioremap_resource()
+where the name field is passed to devm_kasprintf() and dereferenced.
+The struct was never initialized, so the name pointer is whatever
+happened to be on the stack. This has been the case since the original
+checkin of xgene_pmu.c, but it was a recent change to which added the
+use of the name field.

+Subject: [PATCH] xfs: fix boundary test in xfs_attr_shortform_verify
+
+The boundary test for the fixed-offset parts of xfs_attr_sf_entry in
+xfs_attr_shortform_verify is off by one, because the variable array
+at the end is defined as nameval[1] not nameval[].
+Hence we need to subtract 1 from the calculation.
+
+This can be shown by:
+
+# touch file
+# setfattr -n root.a file
+
+and verifications will fail when it's written to disk.
+
+This only matters for a last attribute which has a single-byte name
+and no value, otherwise the combination of namelen & valuelen will
+push endp further out and this test won't fail.
+
+Fixes: 1e1bbd8e7ee06 ("xfs: create structure verifier function for shortform xattrs")
