Linux Kernel Daily: SMB Data Loss Fix and ARM64 Reliability Push
The SMB client fixes a silent writeback data loss regression and bounds retries by mount options, while ARM64 corrects huge-page livelocks and suspend state handling. The broader pattern is failure handling — plus block, audio, and filesystem stabilization for 7.4-rc3.

Hello, this is Linux Kernel Daily for Saturday, November 14th, 2026.
The through-line today is failure handling done right — making sure a transient error doesn't become permanent data loss, a hung device, or a wedged CPU.
First, file and storage reliability, led by the SMB client fixes in merge 3db1c74. Since the move to the shared network filesystem library, a reconnect, lost handle, interrupted wait, or allocation failure could leave writeback pages marked clean with no error, silently dropping writes. The fix retries writeback…
Second, Arm 64 correctness in merge 97d73c8. It fixes a huge-page write fault livelock caused by stale read-only translation entries, saves permission overlay and guarded control stack state across CPU suspend, and ignores guarded control stack mode changes on signal return to avoid hardware and software state…
Third, audio stabilization for the 7.4 release candidate in merge 2800868. Core fixes correct inconsistent sound state after an overrun and drop capture packets with bogus lengths from buggy USB controllers. The rest are device quirks, a memory leak fix, and a build dependency fix for an older P-C-I driver. A single…
What to watch: test SMB…
