.valgrind has been upgraded to upstream version 3.25.1 The upgrade from version 3.24.0 (RHEL 10.0) to the upstream version 3.25.1 (RHEL 10.1) provides the following notable enhancements: *Added support for zstd-compressed debug sections. * Extended to Linux syscalls: landlock*, io_pgetevents, open_tree, move_mount, fsopen, fsconfig, fsmount, fspick, userfaultfd. * Enhanced file-descriptor tracking: `--track-fds=yes` and `--track-fds=all` apply the same behavior to inherited file descriptors as to standard input, standard output, and standard error. * New option `--modify-fds=high` (use with `--track-fds=yes`) allocates higher-numbered descriptors first to help detect descriptor reuse issues. * Helgrind configuration: warnings for `pthread_cond_signal` and `pthread_cond_broadcast` with an unlocked mutex are now controlled by `--check-cond-signal-mutex=yes|no` (default: no). Architecture-specific enhancements: * New IBM Z (`s390x`) NNPA hardware support.
