It only guarantees that the suspend and resume callbacks\nwill not be running when it returns.\n\nHowever, if a .runtime_idle() callback is already running when\npm_runtime_get_sync() is called, the latter will notice that the runtime PM\nstatus of the device is RPM_ACTIVE and it will return right away without\nwaiting for the former to complete.  In fact, it cannot wait for\n.runtime_idle() to complete because it may be called from that callback (it\narguably does not make much sense to do that, but it is not strictly\nprohibited).\n\nThus in general, whoever is providing a .runtime_idle() callback needs\nto protect it from running in parallel with whatever code runs after\npm_runtime_get_sync().  [Note that .runtime_idle() will not start after\npm_runtime_get_sync() has returned, but it may continue running then if it\nhas started earlier.]\n\nOne way to address that race condition is to call pm_runtime_barrier()\nafter pm_runtime_get_sync() (not before it, because a nonzero value of the\nruntime PM usage counter is necessary to prevent runtime PM callbacks from\nbeing invoked) to wait for the .runtime_idle() callback to complete should\nit be running at that point.  A suitable place for doing that is in\npci_device_remove() which calls pm_runtime_get_sync() before removing the\ndriver, so it may as well call pm_runtime_barrier() subsequently, which\nwill prevent the race in question from occurring, not just in the rtsx_pcr\ndriver, but in any PCI drivers providing .runtime_idle() callbacks."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/pci/pci-driver.c"],"versions":[{"version":"f3ec4f87d607f40497afdb5ac03f11e2ea253d52","lessThan":"9a87375bb586515c0af63d5dcdcd58ec4acf20a6","status":"affected","versionType":"git"},{"version":"f3ec4f87d607f40497afdb5ac03f11e2ea253d52","lessThan":"47d8aafcfe313511a98f165a54d0adceb34e54b1","status":"affected","versionType":"git"},{"version":"f3ec4f87d607f40497afdb5ac03f11e2ea253d52","lessThan":"bbe068b24409ef740657215605284fc7cdddd491","status":"affected","versionType":"git"},{"version":"f3ec4f87d607f40497afdb5ac03f11e2ea253d52","lessThan":"7cc94dd36e48879e76ae7a8daea4ff322b7d9674","status":"affected","versionType":"git"},{"version":"f3ec4f87d607f40497afdb5ac03f11e2ea253d52","lessThan":"900b81caf00c89417172afe0e7e49ac4eb110f4b","status":"affected","versionType":"git"},{"version":"f3ec4f87d607f40497afdb5ac03f11e2ea253d52","lessThan":"d86ad8c3e152349454b82f37007ff6ba45f26989","status":"affected","versionType":"git"},{"version":"f3ec4f87d607f40497afdb5ac03f11e2ea253d52","lessThan":"d534198311c345e4b062c4b88bb609efb8bd91d5","status":"affected","versionType":"git"},{"version":"f3ec4f87d607f40497afdb5ac03f11e2ea253d52","lessThan":"6347348c6aba52dda0b33296684cbb627bdc6970","status":"affected","versionType":"git"},{"version":"f3ec4f87d607f40497afdb5ac03f11e2ea253d52","lessThan":"9d5286d4e7f68beab450deddbb6a32edd5ecf4bf","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/pci/pci-driver.c"],"versions":[{"version":"2.6.36","status":"affected"},{"version":"0","lessThan":"2.6.36","status":"unaffected","versionType":"semver"},{"version":"4.19.312","lessThanOrEqual":"4.19.*","status":"unaffected","versionType":"semver"},{"version":"5.4.274","lessThanOrEqual":"5.4.*","status":"unaffected","versionType":"semver"},{"version":"5.10.215","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.154","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.84","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.24","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.7.12","lessThanOrEqual":"6.7.*","status":"unaffected","versionType":"semver"},{"version":"6.8.3","lessThanOrEqual":"6.8.*","status":"unaffected","versionType":"semver"},{"version":"6.9","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.36","versionEndExcluding":"4.19.312"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.36","versionEndExcluding":"5.4.274"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.36","versionEndExcluding":"5.10.215"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.36","versionEndExcluding":"5.15.154"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.36","versionEndExcluding":"6.1.84"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.36","versionEndExcluding":"6.6.24"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.36","versionEndExcluding":"6.7.12"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.36","versionEndExcluding":"6.8.3"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.36","versionEndExcluding":"6.9"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/9a87375bb586515c0af63d5dcdcd58ec4acf20a6"},{"url":"https://git.kernel.org/stable/c/47d8aafcfe313511a98f165a54d0adceb34e54b1"},{"url":"https://git.kernel.org/stable/c/bbe068b24409ef740657215605284fc7cdddd491"},{"url":"https://git.kernel.org/stable/c/7cc94dd36e48879e76ae7a8daea4ff322b7d9674"},{"url":"https://git.kernel.org/stable/c/900b81caf00c89417172afe0e7e49ac4eb110f4b"},{"url":"https://git.kernel.org/stable/c/d86ad8c3e152349454b82f37007ff6ba45f26989"},{"url":"https://git.kernel.org/stable/c/d534198311c345e4b062c4b88bb609efb8bd91d5"},{"url":"https://git.kernel.org/stable/c/6347348c6aba52dda0b33296684cbb627bdc6970"},{"url":"https://git.kernel.org/stable/c/9d5286d4e7f68beab450deddbb6a32edd5ecf4bf"}],"title":"PCI/PM:
