Linux Kernel Daily: RC2 Cleanup Wave
Linus pulled six subsystem fix branches into 7.2-rc2, mostly resource leaks, use-after-free bugs, and one deadlock regression. The common thread is cleanup-path correctness: drivers and core code failing to properly tear down state on removal, suspend, or error.

Good day, it's July 6th, 2026. This is Linux Kernel Daily.
Today's activity is release-cycle housekeeping: Linus merged six fix branches into 7.2-rc2, and the dominant theme across nearly all of them is broken cleanup paths — code that doesn't properly release resources or reset state when things shut down, fail, or get interrupted.
Start with sound. Commit 216a8b2 pulls in a fix for a use-after-free on device disconnect in the US144 Mark 2 driver, plus a related anchor list corruption from a redundant resubmission call. Same branch fixes a clock leak in the R-Car sound driver during suspend and resume. That's three separate teardown bugs in…
The irq branch, in 610533c, is almost entirely this pattern too: a missing chained handler cleanup on module removal in the TS-4800 driver, an OF node reference leak in the ARM GIC v3 ITS driver, and a file node leak on setup failure in the RISC-V IMSIC early driver. Three drivers, three different leak types, same…
Second theme: correctness in concurrent and interrupted execution. The SPI core fix in 9c9330c aborts an active target-mode transfer when the controller suspends, closing a gap where suspend could leave a transfer hanging. The perf…
