And that was again incorrect, for two reasons: # # a) Fast gup and slow gup get reference counts on pages in different # ways and with different goals: see Linus' writeup in commit # cd1adf1b63a1 ("Revert "mm/gup: remove try_get_page(), call # try_get_compound_head() directly""), and # # b) try_grab_compound_head() also has a specific check for # "FOLL_LONGTERM && !is_pinned(page)", that assumes that the caller # can fall back to slow gup. This resulted in new failures, as # recently report by Will McVicker [1]. # # But (a) has problems too, even though they may not have been reported # yet. So just revert this. # # Link: https://lore.kernel.org/r/20220131203504.3458775-1-willmcvicker@google.com [1] # Fixes: 54d516b1d62f ("mm/gup: small refactoring: simplify try_grab_page()") # Reported-and-tested-by: Will McVicker <willmcvicker@google.com> # Cc: Christoph Hellwig <hch@lst.de> # Cc: Minchan Kim <minchan@google.com> # Cc: Matthew Wilcox <willy@infradead.org> # Cc: Christian Borntraeger <borntraeger@de.ibm.com> # Cc: Heiko Carstens <hca@linux.ibm.com> # Cc: Vasily Gorbik <gor@linux.ibm.com> # Cc: stable@vger.kernel.org # 5.15 # Signed-off-by: John Hubbard <jhubbard@nvidia.com> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 c36c04c2e132fc39f6b658bf607aed4425427fd7 # < make -s -j 48 ARCH=um O=/kisskb/build/linus_um-allyesconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 allyesconfig # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_KCOV=n # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig CONFIG_GCC_PLUGIN_CYC_COMPLEXITY=n # Added to kconfig CONFIG_GCC_PLUGIN_SANCOV=n # Added to kconfig CONFIG_GCC_PLUGIN_LATENT_ENTROPY=n # Added to kconfig CONFIG_GCC_PLUGIN_STRUCTLEAK=n # Added to kconfig CONFIG_GCC_PLUGIN_RANDSTRUCT=n # Added to kconfig CONFIG_UML_NET=n # Added to kconfig CONFIG_UML_NET_ETHERTAP=n # Added to kconfig CONFIG_UML_NET_TUNTAP=n # Added to kconfig CONFIG_UML_NET_SLIP=n # Added to kconfig CONFIG_UML_NET_DAEMON=n # Added to kconfig CONFIG_UML_NET_VDE=n # Added to kconfig CONFIG_UML_NET_MCAST=n # Added to kconfig CONFIG_UML_NET_PCAP=n # Added to kconfig CONFIG_UML_NET_SLIRP=n # Added to kconfig CONFIG_GCOV_KERNEL=n # Added to kconfig CONFIG_DEBUG_INFO_BTF=n # Added to kconfig CONFIG_BPF_PRELOAD=n # < make -s -j 48 ARCH=um O=/kisskb/build/linus_um-allyesconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 help # make -s -j 48 ARCH=um O=/kisskb/build/linus_um-allyesconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 olddefconfig .config:12230:warning: override: reassigning to symbol GCC_PLUGIN_SANCOV .config:12233:warning: override: reassigning to symbol GCC_PLUGIN_RANDSTRUCT .config:12235:warning: override: reassigning to symbol UML_NET_ETHERTAP .config:12237:warning: override: reassigning to symbol UML_NET_SLIP .config:12240:warning: override: reassigning to symbol UML_NET_MCAST .config:12242:warning: override: reassigning to symbol UML_NET_SLIRP # make -s -j 48 ARCH=um O=/kisskb/build/linus_um-allyesconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 /kisskb/src/drivers/vfio/pci/vfio_pci_rdwr.c: In function 'vfio_pci_vga_rw': /kisskb/src/drivers/vfio/pci/vfio_pci_rdwr.c:317:11: error: implicit declaration of function 'ioport_map' [-Werror=implicit-function-declaration] iomem = ioport_map(0x3b0, 0x3bb - 0x3b0 + 1); ^ /kisskb/src/drivers/vfio/pci/vfio_pci_rdwr.c:317:9: error: assignment makes pointer from integer without a cast [-Werror=int-conversion] iomem = ioport_map(0x3b0, 0x3bb - 0x3b0 + 1); ^ /kisskb/src/drivers/vfio/pci/vfio_pci_rdwr.c:324:9: error: assignment makes pointer from integer without a cast [-Werror=int-conversion] iomem = ioport_map(0x3c0, 0x3df - 0x3c0 + 1); ^ /kisskb/src/drivers/vfio/pci/vfio_pci_rdwr.c:338:15: error: implicit declaration of function 'ioport_unmap' [-Werror=implicit-function-declaration] is_ioport ? ioport_unmap(iomem) : iounmap(iomem); ^ cc1: all warnings being treated as errors make[4]: * [/kisskb/src/scripts/Makefile.build:288: drivers/vfio/pci/vfio_pci_rdwr.o] Error 1 make[3]: * [/kisskb/src/scripts/Makefile.build:550: drivers/vfio/pci] Error 2 make[3]: * Waiting for unfinished jobs.... make[2]: * [/kisskb/src/scripts/Makefile.build:550: drivers/vfio] Error 2 make[2]: * Waiting for unfinished jobs....
