[PATCH 5.10 472/593] perf scripting python: Fix tuple_set_u64()

From: Greg Kroah-Hartman
Date: Mon Jul 12 2021 - 03:09:18 EST


From: Adrian Hunter <adrian.hunter@xxxxxxxxx>

[ Upstream commit d04c1ff0b3ddd5c0fbbe640996c8eaad279ed1c5 ]

tuple_set_u64() produces a signed value instead of an unsigned value.
That works for database export but not other cases. Rename to
tuple_set_d64() for database export and fix tuple_set_u64().

Fixes: df919b400ad3f ("perf scripting python: Extend interface to export data in a database-friendly way")
