Since this is # meant to preallocate that amount of storage for the file, it can cause # the cache to fill up the disk and hit ENOSPC. # # Fix this by passing the length actually required to go from the current # EOF to the desired EOF. # # Fixes: 7623ed6772de ("cachefiles: Implement cookie resize for truncate") # Reported-by: Jeffle Xu # Signed-off-by: David Howells # Tested-by: Jeff Layton # Reviewed-by: Jeff Layton # cc: linux-cachefs@redhat.com # Link: https://lore.kernel.org/r/164630854858.3665356.17419701804248490708.stgit@warthog.procyon.org.uk # v1 # Signed-off-by: Linus Torvalds # < /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-gcc --version # < /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-ld --version # < git log --format=%s --max-count=1 b08968f196d498b19e9d0841d76a03862258f2d8 # < make -s -j 32 ARCH=arm64 O=/kisskb/build/linus_arm64-allmodconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- allmodconfig # < make -s -j 32 ARCH=arm64 O=/kisskb/build/linus_arm64-allmodconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- help # make -s -j 32 ARCH=arm64 O=/kisskb/build/linus_arm64-allmodconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- olddefconfig # make -s -j 32 ARCH=arm64 O=/kisskb/build/linus_arm64-allmodconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- In file included from /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/../lib/gcc/aarch64-buildroot-linux-gnu/5.4.0/plugin/include/tm.h:27, from /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/../lib/gcc/aarch64-buildroot-linux-gnu/5.4.0/plugin/include/gcc-plugin.h:31, from /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/../lib/gcc/aarch64-buildroot-linux-gnu/5.4.0/plugin/include/plugin.h:23, from /kisskb/src/scripts/gcc-plugins/gcc-common.h:9, from /kisskb/src/scripts/gcc-plugins/latent_entropy_plugin.c:78: /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/../lib/gcc/aarch64-buildroot-linux-gnu/5.4.0/plugin/include/config/elfos.h:102:21: warning: invalid suffix on literal;
