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/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 b08968f196d498b19e9d0841d76a03862258f2d8 # < make -s -j 8 ARCH=x86 O=/kisskb/build/linus_x86-allmodconfig_x86_64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # < make -s -j 8 ARCH=x86 O=/kisskb/build/linus_x86-allmodconfig_x86_64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux- help # make -s -j 8 ARCH=x86 O=/kisskb/build/linus_x86-allmodconfig_x86_64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux- olddefconfig # make -s -j 8 ARCH=x86 O=/kisskb/build/linus_x86-allmodconfig_x86_64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux- vmlinux.o: warning: objtool: mce_start()+0x5c: call to __kasan_check_write() leaves .noinstr.text section vmlinux.o: warning: objtool: mce_gather_info()+0x5f: call to v8086_mode.constprop.0() leaves .noinstr.text section vmlinux.o: warning: objtool: mce_read_aux()+0x8a: call to mca_msr_reg() leaves .noinstr.text section vmlinux.o: warning: objtool: do_machine_check()+0x197: call to mce_no_way_out() leaves .noinstr.text section vmlinux.o: warning: objtool: mce_severity_amd.constprop.0()+0xca: call to mce_severity_amd_smca() leaves .noinstr.text section Completed OK # rm -rf /kisskb/build/linus_x86-allmodconfig_x86_64-gcc11 # Build took: 0:56:19.584121
