Similarly the PCI rescan/remove lock\nwas also taken in sriov_add_vfs() to protect addition of VFs.\n\nThis approach however causes deadlock on trying to remove PFs with SR-IOV\nenabled because PFs disable SR-IOV during removal and this removal happens\nunder the PCI rescan/remove lock. So the original fix had to be reverted.\n\nInstead of taking the PCI rescan/remove lock in sriov_add_vfs() and\nsriov_del_vfs(), fix the race that occurs with SR-IOV enable and disable vs\nhotplug higher up in the callchain by taking the lock in\nsriov_numvfs_store() before calling into the driver's sriov_configure()\ncallback."}],"metrics":{},"references":[{"url":"https://git.kernel.org/stable/c/1047ca2d816994f31e1475e63e0c0b7825599747","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/3cddde484471c602bea04e6f384819d336a1ff84","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/7c37920c96b85ef4255a7acc795e99e63dd38d59","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/97c18f074ff1c12d016a0753072a3afdfa0b9611","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/a5338e365c4559d7b4d7356116b0eb95b12e08d5","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/bea1d373098b22d7142da48750ce5526096425bc","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/d7673ac466eca37ec3e6b7cc9ccdb06de3304e9b","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/f3015627b6e9ddf85cfeaf42405b3c194dde2c36","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"}]}}]}
