bcachefs: grab s_umount only if snapshotting
When I was testing mongodb over bcachefs with compression,
there is a lockdep warning when snapshotting mongodb data volume.
$ cat test.sh
prog=bcachefs
$prog subvolume create /mnt/data
$prog subvolume create /mnt/data/snapshots
while true;do
$prog subvolume snapshot /mnt/data /mnt/data/snapshots/$(date +%s)
sleep 1s
done
$ cat /etc/mongodb.conf
systemLog:
destination: file
logAppend: true
path: /mnt/data/mongod.log
storage:
dbPath: /mnt/data/

When issuing discards, we may need to flush the journal if there's too many buckets that can't be discarded until a journal flush.

media: solo6x10: replace max(a, min(b, c)) by clamp(b, a, c)
This patch replaces max(a, min(b, c)) by clamp(b, a, c) in the solo6x10 driver. This improves the readability and more importantly, for the solo6x10-p2m.c file, this reduces on my system (x86-64, gcc 13): - the preprocessed size from 121 MiB to 4.5 MiB; - the build CPU time from 46.8 s to 1.6 s; - the build memory from 2786 MiB to 98MiB. In fine, this allows this relatively simple C file to be built on a 32-bit system.

execve: open the executable file before doing anything else
No point in allocating a new mm, counting arguments and environment variables etc if we're just going to return ENOENT. This patch does expose the fact that 'do_filp_open()' that execve() uses is still unnecessarily expensive in the failure case, because it allocates the 'struct file *' early, even if the path lookup (which is heavily optimized) fails. So that remains an unnecessary cost in the "no such executable" case, but it's a separate issue. Regardless, I do not want to do _both_ a filename_lookup() and a later do_filp_open() like the origin patch by Josh Triplett did in [1].

This test is also being skipped on several architectures (powerpc, s390x, arm and aarch64) due to other pending issues with intruction breakpoints. - Adjust test case perf record offcpu profiling tests for s390. - Fix 'Setup struct perf_event_attr' fails on s390 on z/VM guest, addressing issues caused by the fallback from cycles to task-clock done in this release. - Fix mask for VG register in the user-regs test. - Use shellcheck on 'perf test' shell scripts automatically to make sure changes don't introduce things it flags as problematic. - Add option to change objdump binary and allow it to be set via 'perf config'. - Add basic 'perf script', 'perf list --json" and 'perf diff' tests. - Basic branch counter support. - Make DSO tests a suite rather than individual. - Remove atomics from test_loop to avoid test failures. - Fix call chain match on powerpc for the record+probe_libc_inet_pton test. - Improve Intel hybrid tests. Vendor event files (JSON): powerpc: - Update datasource event name to fix duplicate events on IBM's Power10. - Add PVN for HX-C2000 CPU with Power8 Architecture. Intel: - Alderlake/rocketlake metric fixes. - Update emeraldrapids events to v1.02. - Update icelakex events to v1.23. - Update sapphirerapids events to v1.17. - Add skx, clx, icx and spr upi bandwidth metric. AMD: - Add Zen 4 memory controller events. RISC-V: - Add StarFive Dubhe-80 and Dubhe-90 JSON files. https://www.starfivetech.com/en/site/cpu-u - Add T-HEAD C9xx JSON file. https://github.com/riscv-software-src/opensbi/blob/master/docs/platform/thead-c9xx.md ARM64: - Remove UTF-8 characters from cmn.json, that were causing build failure in some distros. - Add core PMU events and metrics for Ampere One X. - Rename Ampere One's BPU_FLUSH_MEM_FAULT to GPC_FLUSH_MEM_FAULT libperf: - Rename several perf_cpu_map constructor names to clarify what they really do. - Ditto for some other methods, coping with some issues in their semantics, like perf_cpu_map__empty() -> perf_cpu_map__has_any_cpu_or_is_empty(). - Document perf_cpu_map__nr()'s behavior perf stat: - Exit if parse groups fails. - Combine the -A/--no-aggr and --no-merge options. - Fix help message for --metric-no-threshold option.

This behaviour is similar on ARM64, with its respective set of big.LITTLE processors. - Fix segfault on build_mem_topology() error path. - Fix 'perf mem' error on hybrid related to availability of mem event in a PMU. - Fix missing reference count gets (map, maps) in the db-export code. - Avoid recursively taking env->bpf_progs.lock in the 'perf_env' code. - Use the newly introduced maps__for_each_map() to add missing locking around iteration of 'struct map' entries. - Parse NOTE segments until the build id is found, don't stop on the first one, ELF files may have several such NOTE segments. - Remove 'egrep' usage, its deprecated, use 'grep -E' instead. - Warn first about missing libelf, not libbpf, that depends on libelf. - Use alternative to 'find ... -printf' as this isn't supported in busybox. - Address python 3.6 DeprecationWarning for string scapes. - Fix memory leak in uniq() in libsubcmd. - Fix man page formatting for 'perf lock' - Fix some spelling mistakes. perf tests: - Fail shell tests that needs some symbol in perf itself if it is stripped. These tests check if a symbol is resolved, if some hot function is indeed detected by profiling, etc. - The 'perf test sigtrap' test is currently failing on PREEMPT_RT, skip it if sleeping spinlocks are detected (using BTF) and point to the mailing list discussion about it. This test is also being skipped on several architectures (powerpc, s390x, arm and aarch64) due to other pending issues with intruction breakpoints. - Adjust test case perf record offcpu profiling tests for s390. - Fix 'Setup struct perf_event_attr' fails on s390 on z/VM guest, addressing issues caused by the fallback from cycles to task-clock done in this release. - Fix mask for VG register in the user-regs test. - Use shellcheck on 'perf test' shell scripts automatically to make sure changes don't introduce things it flags as problematic. - Add option to change objdump binary and allow it to be set via 'perf config'. - Add basic 'perf script', 'perf list --json" and 'perf diff' tests. - Basic branch counter support. - Make DSO tests a suite rather than individual. - Remove atomics from test_loop to avoid test failures. - Fix call chain match on powerpc for the record+probe_libc_inet_pton test. - Improve Intel hybrid tests. Vendor event files (JSON): powerpc: - Update datasource event name to fix duplicate events on IBM's Power10. - Add PVN for HX-C2000 CPU with Power8 Architecture.
