[Libguestfs] [PATCH v3 0/1] tools: add '--blocksize' option for C-based tools
From: Nikolay Ivanets <stenavin@gmail.com> This patch depends on changes in 'common' sub-module posted here: https://www.redhat.com/archives/libguestfs/2020-February/msg00150.html v3 fixes issue found during code review: - options now appear in alphabetical order v2: Almost the same as v1 except '--blocksize' option description is moved into a common submodule (similar to key-option.pod). v1 was here: https://www.redhat.com/archives/libguestfs/2020-February/msg00097.html Nikolay Ivanets (1): tools: add '--blocksize' option for C-based tools align/Makefile.am | 1 + align/scan.c | 8 ++++++++ align/virt-alignment-scan.pod | 2 ++ cat/Makefile.am | 1 + cat/cat.c | 8 ++++++++ cat/filesystems.c | 8 ++++++++ cat/log.c | 8 ++++++++ cat/ls.c | 8 ++++++++ cat/tail.c | 8 ++++++++ cat/virt-cat.pod | 2 ++ cat/virt-filesystems.pod | 2 ++ cat/virt-log.pod | 2 ++ cat/virt-ls.pod | 2 ++ cat/virt-tail.pod | 2 ++ df/Makefile.am | 1 + df/main.c | 8 ++++++++ df/virt-df.pod | 2 ++ diff/diff.c | 8 ++++++++ diff/virt-diff.pod | 2 ++ edit/edit.c | 8 ++++++++ edit/virt-edit.pod | 2 ++ fish/fish.c | 8 ++++++++ fish/guestfish.pod | 2 ++ format/Makefile.am | 1 + format/format.c | 8 ++++++++ format/virt-format.pod | 2 ++ fuse/guestmount.c | 8 ++++++++ fuse/guestmount.pod | 2 ++ inspector/inspector.c | 8 ++++++++ inspector/virt-inspector.pod | 2 ++ rescue/Makefile.am | 1 + rescue/rescue.c | 8 ++++++++ rescue/virt-rescue.pod | 2 ++ 33 files changed, 145 insertions(+) -- 2.17.2

Re: [Libguestfs] [PATCH v3 1/1] tools: add '--blocksize' option for C-based tools
There were a bunch of test failures basically in all the *-docs.sh tests. I have fixed these. I have pushed this one and the related change to common/.
