+
+ KVM: x86: Rename kvm_cache_regs.h => regs.h
+
+ Rename kvm_cache_regs.h to simply regs.h, as the "cache" nomenclature is
+ already a lie (the file deals with state/registers that aren't cached per
+ se), and so that more code/functionality can be landed in the header
+ without making it a truly horrible misnomer.
+
+ Deliberately drop the kvm_ prefix/namespace to align with other "local"
+ headers, and to further differentiate regs.h from the public/global
+ arch/x86/include/asm/kvm_vcpu_regs.h, which sadly needs to stay in asm/
+ so that the number of registers can be referenced by kvm_vcpu_arch.
+
+ No functional change intended.

+
+ btrfs: tracepoints: pass a transaction handle to transaction commit event
+
+ The transaction commit tracepoint prints fs_info->generation as if it
+ were the ID of the committed transaction but this does not always match
+ that ID. This is because the trace point is called in the transaction
+ commit path after the transaction is in the TRANS_STATE_COMPLETED state,
+ which means another transaction may have already started (which can happen
+ as soon as the transaction state was set to TRANS_STATE_UNBLOCKED), in
+ which case fs_info->generation was incremented and does not correspond
+ to the committed transaction anymore.
+
+ So fix this by passing a transaction handle to the trace event instead of
+ fs_info. This will also allow later for the trace event to dump other
+ useful information about the transaction.

+
+ btrfs: tracepoints: trace transaction states during commit phase
+
+ Currently the trace event is fired only when a transaction is fully
+ complete (its state is TRANS_STATE_COMPLETED). However during a
+ transaction commit we go through several states and as soon as the
+ state reaches TRANS_STATE_UNBLOCKED, another transaction can start.
+ Therefore it's useful to track every transaction state changed during
+ the commit of a transaction, so that we can see if a new transaction
+ is started before the current one is completed. Add the transaction
+ state to the transaction commit event and call the event everytime
+ we change the transaction state during commit.

+ Date: Mon Mar 23 01:27:25 2026 +0000
+
+ string: Remove strncpy() from the kernel
+
+ strncpy() has been a persistent source of bugs due to its ambiguous
+ intended usage and frequently counter-intuitive semantics: it may not
+ NUL-terminate the destination, and it unconditionally zero-pads to the
+ full length, which isn't always needed. All former callers have been
+ migrated[1] to:
+
+ - strscpy() for NUL-terminated destinations
+ - strscpy_pad() for NUL-terminated destinations needing zero-padding
+ - strtomem_pad() for non-NUL-terminated fixed-width fields
+ - memcpy_and_pad() for bounded copies with explicit padding
+ - memcpy() for known-length copies
+
+ Remove the generic implementation, its declaration, the FORTIFY_SOURCE
+ wrapper, and associated tests.
+
+ commit 458a3bf82df4fe1f951d0f52b1e0c1e9d5a88a3b
+ Author: Tobin C. Harding <tobin@kernel.org>
+ Date: Fri Apr 5 12:58:58 2019 +1100
+
+ lib/string: Add strscpy_pad() function
+
+ We have a function to copy strings safely and we have a function to copy
+ strings and zero the tail of the destination (if source string is
+ shorter than destination buffer) but we do not have a function to do
+ both at once. This means developers must write this themselves if they
+ desire this functionality. This is a chore, and also leaves us open to
+ off by one errors unnecessarily.
+
+ Add a function that calls strscpy() then memset()s the tail to zero if
+ the source string is shorter than the destination buffer.
