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/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-gcc --version # < /opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-ld --version # < git log --format=%s --max-count=1 c36c04c2e132fc39f6b658bf607aed4425427fd7 # < make -s -j 32 ARCH=sparc O=/kisskb/build/linus_sparc-allmodconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- allmodconfig # Added to kconfig CONFIG_64BIT=n # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_HAVE_FTRACE_MCOUNT_RECORD=n # Added to kconfig CONFIG_SAMPLES=n # Added to kconfig CONFIG_MODULE_SIG=n # < make -s -j 32 ARCH=sparc O=/kisskb/build/linus_sparc-allmodconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- help # make -s -j 32 ARCH=sparc O=/kisskb/build/linus_sparc-allmodconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- olddefconfig # make -s -j 32 ARCH=sparc O=/kisskb/build/linus_sparc-allmodconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- <stdin>:1517:2: warning: #warning syscall clone3 not implemented [-Wcpp] WARNING: modpost: EXPORT symbol "bzero_1page" [vmlinux] version ...
