Good morning. This is your Linux Kernel Daily weekly recap for March 30th through April 6th, 2026.
Zero pull requests were merged this week, with 30 additional commits landing in the mainline tree.
Starting with fixes, Lance Yang addressed a critical race condition in the deferred split queue during memory migration that was causing crashes detected by syzkaller. The fix ensures proper queue state management before folios become visible again. Lorenzo Stoakes from Oracle resolved a lock tracking issue in…
RISC-V received significant attention through Linus Torvalds' merge of fixes from Paul Walmsley. These address a CONFIG_SPARSEMEM crash on 32-bit RISC-V systems, prevent runtime const infrastructure misuse by modules, and fix ACPI IOMMU shutdown problems. Additional RISC-V fixes include proper CPU pointer masking…
Architecture-specific fixes also landed for m68k and x86. Daniel Palmer fixed task info flag handling for 68000 processors, addressing syscall decision logic that was checking incorrect word boundaries. Ronan Pigott resolved a minor x86 issue where the split_lock_detect command line parameter was generating unknown…
The bulk of commits came from Lorenzo Stoakes'…
