Siddh Raman Pant 26ebeffff2 Revert "tracing/trigger: Fix to return error if failed to alloc snapshot" ... This reverts commit 56cfbe6071 which is commit 0958b33ef5 upstream. The change has an incorrect assumption about the return value because in the current stable trees for versions 5.15 and before, the following commit responsible for making 0 a success value is not present: b8cc44a4d3 ("tracing: Remove logic for registering multiple event triggers at a time") The return value should be 0 on failure in the current tree, because in the functions event_trigger_callback() and event_enable_trigger_func(), we have: ret = cmd_ops->reg(glob, trigger_ops, trigger_data, file); /* * The above returns on success the # of functions enabled, * but if it didn't find any functions it returns zero. * Consider no functions a failure too. */ if (!ret) { ret = -ENOENT; Cc: stable@kernel.org # 5.15, 5.10, 5.4, 4.19 Signed-off-by: Siddh Raman Pant <siddh.raman.pant@oracle.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2024-05-02 16:23:36 +02:00
