Good day, and welcome to Linux Kernel Daily for September 15th, 2026.
Today's activity is all fixes, no features — and the through-line is race conditions and user-triggerable bugs getting cleaned up before release.
The biggest batch comes from RDMA, merged by Linus in commit 01414b7. Jason Gunthorpe's pull brings twenty-eight fixes, and the pattern is notable: multiple remotely triggerable races in the SIW and RXE drivers, a user-triggerable race in U-C-M-A around multicast handling, and a security fix in bnxt_re to stop…
Memory management saw its own hardening pass in commit 164f652, Andrew Morton's fourteen hotfixes. Highlights include a swap usage counter bug where a status bit collided with the real usage count — a subtle correctness issue — plus a fix for incorrect memory accounting during failed memory-map preparation, and an…
Two smaller but concrete fixes rounded things out. The nfsd pull in 5878583 fixes how the P-NFS export flag is handled over the netlink interface — a correctness fix for cluster-aware NFS setups. And the 9p filesystem fix in 59826bc addresses a regression from version 7.1 where cached file size wasn't updating…
What to remember: this cycle's fixes lean…
