The timerlat tracer provides an interface for any application to wait for the timerlat's periodic wakeup. Currently, rtla timerlat uses it to dispatch its user-space workload (-u option). But as the tracer interface is generic, rtla timerlat can also be used to monitor any workload that uses it. For example, a user might place their own workload to wait on the tracer interface, and monitor the results with rtla timerlat. Add the -U option to rtla timerlat top and hist. With this option, rtla timerlat will not dispatch its workload but only setting up the system, waiting for a user to dispatch its workload. The sample code in this patch is an example of python application that loops in the timerlat tracer fd. To use it, dispatch: # rtla timerlat -U In a terminal, then run the python program on another terminal, specifying the CPU to run it. For example, setting on CPU 1: #./timerlat_load.py 1 Then rtla timerlat will start printing the statistics of the ./timerlat_load.py app. An interesting point is that the "Ret user Timer Latency" value is the overall response time of the load. The sample load does a memory copy to exemplify that. The stop tracing options on rtla timerlat works in this setup as well, including auto analysis.

Use tools/build/ makefiles to build rtla, inheriting the benefits of it. For example, having a proper way to handle dependencies. rtla is built using perf infra-structure when building inside the kernel tree. At this point, rtla diverges from perf in two points: Documentation and tarball generation/build. At the documentation level, rtla is one step ahead, placing the documentation at Documentation/tools/rtla/, using the same build tools as kernel documentation. The idea is to move perf documentation to the same scheme and then share the same makefiles. rtla has a tarball target that the (old) RHEL8 uses. The tarball was kept using a simple standalone makefile for compatibility. The standalone makefile shares most of the code, e.g., flags, with regular buildings. The tarball method was set as deprecated. If necessary, we can make a rtla tarball like perf, which includes the entire tools/build. But this would also require changes in the user side (the directory structure changes, and probably the deps to build the package). Inspired on perf and objtool.

Pull more s390 updates from Heiko Carstens: - Various virtual vs physical address usage fixes - Add new bitwise types and helper functions and use them in s390 specific drivers and code to make it easier to find virtual vs physical address usage bugs. Right now virtual and physical addresses are identical for s390, except for module, vmalloc, and similar areas. This will be changed, hopefully with the next merge window, so that e.g. the kernel image and modules will be located close to each other, allowing for direct branches and also for some other simplifications. As a prerequisite this requires to fix all misuses of virtual and physical addresses. As it turned out people are so used to the concept that virtual and physical addresses are the same, that new bugs got added to code which was already fixed. In order to avoid that even more code gets merged which adds such bugs add and use new bitwise types, so that sparse can be used to find such usage bugs. Most likely the new types can go away again after some time - Provide a simple ARCH_HAS_DEBUG_VIRTUAL implementation - Fix kprobe branch handling: if an out-of-line single stepped relative branch instruction has a target address within a certain address area in the entry code, the program check handler may incorrectly execute cleanup code as if KVM code was executed, leading to crashes - Fix reference counting of zcrypt card objects - Various other small fixes and cleanups * tag 's390-6.9-2' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (41 commits) s390/entry: compare gmap asce to determine guest/host fault s390/entry: remove OUTSIDE macro s390/entry: add CIF_SIE flag and remove sie64a() address check s390/cio: use while (i--) pattern to clean up s390/raw3270: make class3270 constant s390/raw3270: improve raw3270_init() readability s390/tape: make tape_class constant s390/vmlogrdr: make vmlogrdr_class constant s390/vmur: make vmur_class constant s390/zcrypt: make zcrypt_class constant s390/mm: provide simple ARCH_HAS_DEBUG_VIRTUAL support s390/vfio_ccw_cp: use new address translation helpers s390/iucv: use new address translation helpers s390/ctcm: use new address translation helpers s390/lcs: use new address translation helpers s390/qeth: use new address translation helpers s390/zfcp: use new address translation helpers s390/tape: fix virtual vs physical address confusion s390/3270: use new address translation helpers s390/3215: use new address translation helpers ...

As __assign_str() no longer uses its "src" parameter, there's a check to make sure nothing depends on it being different than what was passed to __string(). It originally just compared the pointer passed to __string() with the pointer passed into __assign_str() via the "src" parameter. But there's a couple of outliers that just pass in a quoted string constant, where comparing the pointers is UB to the compiler, as the compiler is free to create multiple copies of the same string constant. Instead, just use strcmp(). It may slow down the trace event, but this will eventually be removed. Also, fix the issue of passing NULL to strcmp() by adding a WARN_ON() to make sure that both "src" and the pointer saved in __string() are either both NULL or have content, and then checking if "src" is not NULL before performing the strcmp().

Pull ata fix from Niklas Cassel: "A single fix for ASMedia HBAs. These HBAs do not indicate that they support SATA Port Multipliers CAP.SPM (Supports Port Multiplier) is not set. Likewise, they do not allow you to probe the devices behind an attached PMP, as defined according to the SATA-IO PMP specification. Instead, they have decided to implement their own version of PMP, and because of this, plugging in a PMP actually works, even if the HBA claims that it does not support PMP. Revert a recent quirk for these HBAs, as that breaks ASMedia's own implementation of PMP. Unfortunately, this will once again give some users of these HBAs significantly increased boot time. However, a longer boot time for some, is the lesser evil compared to some other users not being able to detect their drives at all" * tag 'ata-6.9-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/libata/linux: ahci: asm1064: asm1166: don't limit reported ports

If reading the ACPI _PLD port location object fails, or the port doesn't have a _PLD ACPI object then the *pld pointer will remain uninitialized and oops when freed. The patch that caused this is currently in next, on its way to v6.9. So no need to add this to stable or current 6.8 kernel. Reported-by:

When sync or dir_sync is enabled, there is no need to sync the parent directory's inode if only for updating its timestamp. 1. If an unexpected power failure occurs, the timestamp of the parent directory is not updated to the storage, which has no impact on the user. 2. The number of writes will be greatly reduced, which can not only improve performance, but also prolong device life. Signed-off-by:

Before this conversion, each dentry traversed needs to be read from the storage device or page cache. There are at least 16 dentries in a sector. This will result in frequent page cache searches. After this conversion, if all directory entries in a sector are used, the sector only needs to be read once. Signed-off-by:

exfat_init_ext_entry() is an init function, it's a bit strange to free cluster in it. And the argument 'inode' will be removed from exfat_init_ext_entry(). So this commit changes to free the cluster in exfat_remove_entries(). Code refinement, no functional changes. Signed-off-by:
