This is Linux Kernel Daily for the week of July 20th through 27th, 2026.
Zero pull request activity items, 30 additional commits this week — all of it merge traffic from subsystem maintainers into the mainline tree, standard for this point in the 7.2 release candidate cycle.
The dominant pattern this week is concurrency hardening. Across nearly every subsystem pulled in, the fixes target races, use-after-free conditions, and lock ordering problems that only surface under real-world timing.
In the virtual file system pull, commit 4235cb2, Christian Brauner's tree fixes a deadlock where thawing a filesystem could reacquire a lock it already held, plus an event poll fix that pins files during reverse-path checks now that file structures can be freed and recycled underneath a running check. The same pull…
Tracing saw a parallel cleanup. Steven Rostedt's pull, commit 864be12, fixes a use-after-free in the event-enable trigger by deferring cleanup until after synchronization completes, adds a mutex around the trace filter parser to stop concurrent writes from corrupting it, and fixes a stale per-CPU pointer in…
USB and block pulls follow the same theme at the driver level. The USB fixes,…
