2025-07-09kthread: update comment for __to_kthreadJiazi Li
With commit 343f4c49f243 ("kthread: Don't allocate kthread_struct for init and umh") and commit 753550eb0ce1 ("fork: Explicitly set PF_KTHREAD"), umh task no longer have struct kthread and PF_KTHREAD flag. Update the comment to describe what the current rules are to detect is something is a kthread.

2025-07-09lib: test_objagg: split test_hints_case() into two functionsArnd Bergmann
With sanitizers enabled, this function uses a lot of stack, causing a harmless warning: lib/test_objagg.c: In function 'test_hints_case.constprop': lib/test_objagg.c:994:1: error: the frame size of 1440 bytes is larger than 1408 bytes [-Werror=frame-larger-than=] Most of this is from the two 'struct world' structures. Since most of the work in this function is duplicated for the two, split it up into separate functions that each use one of them. The combined stack usage is still the same here, but there is no warning any more, and the code is still safe because of the known call chain.

2025-07-09ocfs2: remove redundant NULL check in rename pathLong Li
The code checks newfe_bh for NULL after it has already been dereferenced to access b_data. This NULL check is unnecessary for two reasons: 1. If ocfs2_inode_lock() succeeds (returns >= 0), newfe_bh is guaranteed to be valid. 2. We've already dereferenced newfe_bh to access b_data, so it must be non-NULL at this point. Remove the redundant NULL check in the trace_ocfs2_rename_over_existing() call to improve code clarity.

2025-07-09uprobes: revert ref_ctr_offset in uprobe_unregister error pathJiri Olsa
There's error path that could lead to inactive uprobe: 1) uprobe_register succeeds - updates instruction to int3 and changes ref_ctr from 0 to 1 2) uprobe_unregister fails - int3 stays in place, but ref_ctr is changed to 0 (it's not restored to 1 in the fail path) uprobe is leaked 3) another uprobe_register comes and re-uses the leaked uprobe and succeds - but int3 is already in place, so ref_ctr update is skipped and it stays 0 - uprobe CAN NOT be triggered now 4) uprobe_unregister fails because ref_ctr value is unexpected Fix this by reverting the updated ref_ctr value back to 1 in step 2), which is the case when uprobe_unregister fails (int3 stays in place), but we have already updated refctr. The new scenario will go as follows: 1) uprobe_register succeeds - updates instruction to int3 and changes ref_ctr from 0 to 1 2) uprobe_unregister fails - int3 stays in place and ref_ctr is reverted to 1.. uprobe is leaked 3) another uprobe_register comes and re-uses the leaked uprobe and succeds - but int3 is already in place, so ref_ctr update is skipped and it stays 1 - uprobe CAN be triggered now 4) uprobe_unregister succeeds Link: https://lkml.kernel.org/r/20250514101809.2010193-1-jolsa@kernel.org Fixes: 1cc33161a83d ("uprobes: Support SDT markers having reference count (semaphore)") Signed-off-by: Jiri Olsa <jolsa@kernel.org> Acked-by: David Hildenbrand <david@redhat.com> Acked-by: Oleg Nesterov <oleg@redhat.com> Suggested-by: Oleg Nesterov <oleg@redhat.com> Cc: Andrii Nakryiko <andrii@kernel.org> Cc: "Masami Hiramatsu (Google)" <mhiramat@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>

2025-07-09relayfs: support a counter tracking if data is too big to writeJason Xing
It really doesn't matter if the user/admin knows what the last too big value is. Record how many times this case is triggered would be helpful. Solve the existing issue where relay_reset() doesn't restore the value. Store the counter in the per-cpu buffer structure instead of the global buffer structure. It also solves the racy condition which is likely to happen when a few of per-cpu buffers encounter the too big data case and then access the global field last_toobig without lock protection. Remove the printk in relay_close() since kernel module can directly call relay_stats() as they want.

2025-07-09relayfs: support a counter tracking if per-cpu buffers is fullJason Xing
When using relay mechanism, we often encounter the case where new data are lost or old unconsumed data are overwritten because of slow reader. Add 'full' field in per-cpu buffer structure to detect if the above case is happening. Relay has two modes: 1) non-overwrite mode, 2) overwrite mode. So buffer being full here respectively means: 1) relayfs doesn't intend to accept new data and then simply drop them, or 2) relayfs is going to start over again and overwrite old unread data with new data. Note: this counter doesn't need any explicit lock to protect from being modified by different threads for the better performance consideration. Writers calling __relay_write/relay_write should consider how to use the lock and ensure it performs under the lock protection, thus it's not necessary to add a new small lock here.

2025-07-09relayfs: abolish prev_paddingJason Xing
Patch series "relayfs: misc changes", v5. The series mostly focuses on the error counters which helps every user debug their own kernel module. This patch (of 5): prev_padding represents the unused space of certain subbuffer. If the content of a call of relay_write() exceeds the limit of the remainder of this subbuffer, it will skip storing in the rest space and record the start point as buf->prev_padding in relay_switch_subbuf(). Since the buf is a per-cpu big buffer, the point of prev_padding as a global value for the whole buffer instead of a single subbuffer (whose padding info is stored in buf->padding[]) seems meaningless from the real use cases, so we don't bother to record it any more.

2025-07-09fork: define a local GFP_VMAP_STACKLinus Walleij
The current allocation of VMAP stack memory is using (THREADINFO_GFP & ~__GFP_ACCOUNT) which is a complicated way of saying (GFP_KERNEL | __GFP_ZERO): <linux/thread_info.h>: define THREADINFO_GFP (GFP_KERNEL_ACCOUNT | __GFP_ZERO) <linux/gfp_types.h>: define GFP_KERNEL_ACCOUNT (GFP_KERNEL | __GFP_ACCOUNT) This is an unfortunate side-effect of independent changes blurring the picture: commit 19809c2da28aee5860ad9a2eff760730a0710df0 changed (THREADINFO_GFP | __GFP_HIGHMEM) to just THREADINFO_GFP since highmem became implicit. commit 9b6f7e163cd0f468d1b9696b785659d3c27c8667 then added stack caching and rewrote the allocation to (THREADINFO_GFP & ~__GFP_ACCOUNT) as cached stacks need to be accounted separately. However that code, when it eventually accounts the memory does this: ret = memcg_kmem_charge(vm->pages[i], GFP_KERNEL, 0) so the memory is charged as a GFP_KERNEL allocation. Define a unique GFP_VMAP_STACK to use GFP_KERNEL | __GFP_ZERO and move the comment there.
