Good day, and welcome to Linux Kernel Daily for August 13th, 2026.
Today's activity is light but focused: one merge commit, three fixes, all landing in the SCSI subsystem. The throughline here is error handling correctness — each fix addresses a case where the system's failure-recovery logic was itself the source of a problem.
Start with the door-locking fix in SCSI core. The function handling error recovery for removable media devices was blocking on tag allocation, which could lead to a deadlock. That's a real reliability concern — error handling code that hangs defeats its own purpose, since a stuck error handler can stall the wider…
Next, the power management pairing fix, also in SCSI core. This corrects a mismatch between runtime power management "get" and "put" calls during error handling. Unpaired power management calls are a classic source of devices that won't suspend properly, or reference-count leaks that only surface under specific…
Rounding it out, a smaller fix in the SCSI debug driver, correcting a negated comparison in a memory-compare check. Lower stakes than the other two, but part of the same pattern: subtle logic bugs in code that's meant to simulate or handle…
