Linux Kernel Daily: Late-Cycle Fixes Converge on Resource Leaks and Error Handling
Four late-stage merges for the 7.2 cycle land fixes across ARC, SCSI, I2C, and S390, with a clear pattern of resource leak and use-after-free fixes in driver error paths. Two security-adjacent hardening fixes also landed in S390.

Good day. It's July 19th, 2026, and this is Linux Kernel Daily.
Today's activity is all release-cycle housekeeping, four merge commits from Linus Torvalds pulling in fixes ahead of 7.2. The throughline across nearly all of them: resource leaks and use-after-free bugs in error and failure paths.
Start with SCSI, the largest batch, commit f2ec631. The headline fix reworks scsi_schedule_eh so error handler wakeups happen reliably, closing a race that could hang error handling in both libata and SAS drivers. Around that core fix are a cluster of leak fixes: a DMA mapping leak in HPSA's reset path, a refcount…
I2C echoes the same pattern. Commit ba6bd0d fixes a use-after-free in the Mellanox driver's resource initialization, plus bus-locking fixes in the i2c-imx driver when handling zero-length SMBus block reads, both in interrupt and atomic contexts. Same category of bug: incomplete handling of edge cases in transfer…
S390 brings the two fixes with direct security relevance, commit c6859ee. One adds a missing speculation barrier when using a user-controlled event number as an array index in the performance counter code, standard Spectre-style hardening. The other fixes checksum…
