Message-ID: <20251109095416.2428351-1-nogunix@gmail.com> Date: Sun, 9 Nov 2025 18:54:16 +0900 From: Masaharu Noguchi <nogunix@...il.com> To: jaegeuk@...nel.org, chao@...nel.org Cc: corbet@....net, linux-f2fs-devel@...ts.sourceforge.net, linux-doc@...r.kernel.org, linux-kernel@...r.kernel.org, akiyks@...il.com, nogunix@...il.com Subject: [PATCH v2] Documentation: f2fs: wrap tables in literal code blocks Sphinx LaTeX builder fails with the following error when it tries to turn the ASCII tables in f2fs.rst into nested longtables: Markup is unsupported in LaTeX: filesystems/f2fs:: longtable does not support nesting a table. Wrap the tables in literal code blocks so that Sphinx renders them as verbatim text instead. This prevents the LaTeX builder from attempting unsupported table nesting and fixes the pdfdocs build. Akira Yokosawa pointed out that the in-development Sphinx 8.3 latex builder already handles these nested tables. I still want to fix the current documentation because Sphinx 8.3 is not released yet, and the LaTeX build on the stable 8.2.x series (which also requires "docutils<0.22" for now) remains broken without this change. Link: https://lore.kernel.org/lkml/20251011172415.114599-1-nogunix@gmail.com/ Changes in v2: - wrap the compression level table in a literal block and add the missing blank lines so docutils no longer warns about malformed tables - consistently use ``.. code-block:: none`` for the other ASCII tables that previously triggered the LaTeX error Signed-off-by: Masaharu Noguchi <nogunix@...il.com> --- Documentation/filesystems/f2fs.rst | 115 +++++++++++++++-------------- 1 file changed, 61 insertions(+), 54 deletions(-) diff --git a/Documentation/filesystems/f2fs.rst b/Documentation/filesystems/f2fs.rst index a8d02fe5be83..07b8e752476d 100644 --- a/Documentation/filesystems/f2fs.rst +++ b/Documentation/filesystems/f2fs.rst @@ -188,34 +188,36 @@ fault_type=%d Support configuring fault injection type, should be enabled with fault_injection option, fault type value is shown below, it supports single or combined type. - =========================== ========== - Type_Name Type_Value - =========================== ========== - FAULT_KMALLOC 0x00000001 - FAULT_KVMALLOC 0x00000002 - FAULT_PAGE_ALLOC 0x00000004 - FAULT_PAGE_GET 0x00000008 - FAULT_ALLOC_BIO 0x00000010 (obsolete) - FAULT_ALLOC_NID 0x00000020 - FAULT_ORPHAN 0x00000040 - FAULT_BLOCK 0x00000080 - FAULT_DIR_DEPTH 0x00000100 - FAULT_EVICT_INODE 0x00000200 - FAULT_TRUNCATE 0x00000400 - FAULT_READ_IO 0x00000800 - FAULT_CHECKPOINT 0x00001000 - FAULT_DISCARD 0x00002000 - FAULT_WRITE_IO 0x00004000 - FAULT_SLAB_ALLOC 0x00008000 - FAULT_DQUOT_INIT 0x00010000 - FAULT_LOCK_OP 0x00020000 - FAULT_BLKADDR_VALIDITY 0x00040000 - FAULT_BLKADDR_CONSISTENCE 0x00080000 - FAULT_NO_SEGMENT 0x00100000 - FAULT_INCONSISTENT_FOOTER 0x00200000 - FAULT_TIMEOUT 0x00400000 (1000ms) - FAULT_VMALLOC 0x00800000 - =========================== ========== + .. code-block:: none + + =========================== ========== + Type_Name Type_Value + =========================== ========== + FAULT_KMALLOC 0x00000001 + FAULT_KVMALLOC 0x00000002 + FAULT_PAGE_ALLOC 0x00000004 + FAULT_PAGE_GET 0x00000008 + FAULT_ALLOC_BIO 0x00000010 (obsolete) + FAULT_ALLOC_NID 0x00000020 + FAULT_ORPHAN 0x00000040 + FAULT_BLOCK 0x00000080 + FAULT_DIR_DEPTH 0x00000100 + FAULT_EVICT_INODE 0x00000200 + FAULT_TRUNCATE 0x00000400 + FAULT_READ_IO 0x00000800 + FAULT_CHECKPOINT 0x00001000 + FAULT_DISCARD 0x00002000 + FAULT_WRITE_IO 0x00004000 + FAULT_SLAB_ALLOC 0x00008000 + FAULT_DQUOT_INIT 0x00010000 + FAULT_LOCK_OP 0x00020000 + FAULT_BLKADDR_VALIDITY 0x00040000 + FAULT_BLKADDR_CONSISTENCE 0x00080000 + FAULT_NO_SEGMENT 0x00100000 + FAULT_INCONSISTENT_FOOTER 0x00200000 + FAULT_TIMEOUT 0x00400000 (1000ms) + FAULT_VMALLOC 0x00800000 + =========================== ========== mode=%s Control block allocation mode which supports "adaptive" and "lfs".
