It seemed to get # dropped amid the discussion of other related changes, but this # part seems obviously correct on its own, so I've picked it up and # sent it, for expediency. # # Fixes: 64d2ab32efe3 ("vfs: fix put_compat_statfs64() does not handle errors") # Signed-off-by: Eric Sandeen <sandeen@redhat.com> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/br-xtensa-full-2016.08-613-ge98b4dd/bin/xtensa-linux-gcc --version # < /opt/cross/kisskb/br-xtensa-full-2016.08-613-ge98b4dd/bin/xtensa-linux-ld --version # < git log --format=%s --max-count=1 cc3a7bfe62b947b423fcb2cfe89fcba92bf48fa3 # < make -s -j 24 ARCH=xtensa O=/kisskb/build/linus_xtensa-defconfig_xtensa CROSS_COMPILE=/opt/cross/kisskb/br-xtensa-full-2016.08-613-ge98b4dd/bin/xtensa-linux- defconfig # make -s -j 24 ARCH=xtensa O=/kisskb/build/linus_xtensa-defconfig_xtensa CROSS_COMPILE=/opt/cross/kisskb/br-xtensa-full-2016.08-613-ge98b4dd/bin/xtensa-linux- Completed OK # rm -rf /kisskb/build/linus_xtensa-defconfig_xtensa # Build took: 0:00:33.930012
