A task in another thread group sharing the file table could register an mq_notify() and exit without closing the queue. The registration was never torn down and pinned the notification skb, the netlink socket, a pid reference and a user namespace reference forever. Stale registrations are released on inode eviction now. /* Testing */ No build failures or warnings were observed. /* Conflicts */ Merge conflicts with mainline ============================= No known conflicts. Merge conflicts with other trees ================================ No known conflicts. The following changes since commit cee9395acd8043be0644b25c34bfa86623f2b935: Linux 7.3-rc1 (2026-08-30 13:34:40 -0700) are available in the Git repository at: git@gitolite.kernel.org:pub/scm/linux/kernel/git/vfs/vfs tags/ipc-7.4-rc1.misc for you to fetch changes up to eb85469f0dd69ca145d63117450e14c31f67f698: ipc/mqueue: release notification resources during inode eviction (2026-08-31 12:30:30 +0200) ---------------------------------------------------------------- ipc-7.4-rc1.misc Please consider pulling these changes from the signed ipc-7.4-rc1.misc tag.
