There are lots of plain text documents under Documentation/filesystems.
Manually convert several of those to ReST and add them to the index file.

Manually convert several of those to ReST and add them to the index file.

+========
+
+OMFS is a filesystem created by SonicBlue for use in the ReplayTV DVR
+and Rio Karma MP3 player. The filesystem is extent-based, utilizing
+block sizes from 2k to 8k, with hash-based directories. This
+filesystem driver may be used to read and write disks from these
+devices.
+
+Note, it is not recommended that this FS be used in place of a general
+filesystem for your own streaming media device. Native Linux filesystems
+will likely perform better.
+
+More information is available at:
+
+ http://linux-karma.sf.net/
+
+Various utilities, including mkomfs and omfsck, are included with
+omfsprogs, available at:
+
+ http://bobcopeland.com/karma/
+
+Instructions are included in its README.
+
+Options
+=======
+
+OMFS supports the following mount-time options:
+
+ ============ ========================================
+ uid=n make all files owned by specified user
+ gid=n make all files owned by specified group
+ umask=xxx set permission umask to xxx
+ fmask=xxx set umask to xxx for files
+ dmask=xxx set umask to xxx for directories
+ ============ ========================================
+
+Disk format
+===========
+
+OMFS discriminates between "sysblocks" and normal data blocks. The sysblock
+group consists of super block information, file metadata, directory structures,
+and extents. Each sysblock has a header containing CRCs of the entire
+sysblock, and may be mirrored in successive blocks on the disk. A sysblock may
+have a smaller size than a data block, but since they are both addressed by the
+same 64-bit block number, any remaining space in the smaller sysblock is
+unused.
+
+Sysblock header information::
+
+ struct omfs_header {
+ __be64 h_self; /* FS block where this is located */
+ __be32 h_body_size; /* size of useful data after header */
+ __be16 h_crc; /* crc-ccitt of body_size bytes */
+ char h_fill1[2];
+ u8 h_version; /* version, always 1 */
+ char h_type; /* OMFS_INODE_X */
+ u8 h_magic; /* OMFS_IMAGIC */
+ u8 h_check_xor; /* XOR of header bytes before this */
+ __be32 h_fill2;
+ };
+
+Files and directories are both represented by omfs_inode::
+
+ struct omfs_inode {
+ struct omfs_header i_head; /* header */
+ __be64 i_parent; /* parent containing this inode */
+ __be64 i_sibling; /* next inode in hash bucket */
+ __be64 i_ctime; /* ctime, in milliseconds */
+ char i_fill1[35];
+ char i_type; /* OMFS_[DIR,FILE] */
+ __be32 i_fill2;
+ char i_fill3[64];
+ char i_name[OMFS_NAMELEN]; /* filename */
+ __be64 i_size; /* size of file, in bytes */
+ };
+
+Directories in OMFS are implemented as a large hash table. Filenames are
+hashed then prepended into the bucket list beginning at OMFS_DIR_START.
+Lookup requires hashing the filename, then seeking across i_sibling pointers
+until a match is found on i_name. Empty buckets are represented by block
+pointers with all-1s (~0).
+
+A file is an omfs_inode structure followed by an extent table beginning at
+OMFS_EXTENT_START::
+
+ struct omfs_extent_entry {
+ __be64 e_cluster; /* start location of a set of blocks */
+ __be64 e_blocks; /* number of blocks after e_cluster */
+ };
+
+ struct omfs_extent {
+ __be64 e_next; /* next extent table location */
+ __be32 e_extent_count; /* total # extents in this table */
+ __be32 e_fill;
+ struct omfs_extent_entry e_entry; /* start of extent entries */
+ };
+
+Each extent holds the block offset followed by number of blocks allocated to
+the extent. The final extent in each table is a terminator with e_cluster
+being ~0 and e_blocks being ones'-complement of the total number of blocks
+in the table.
+
+If this table overflows, a continuation inode is written and pointed to by
+e_next. These have a header but lack the rest of the inode structure.

doc patches go through his tree.

I think at least 90% of this material needs to be in admin-guide. Should
we create Documentation/admin-guide/filesystems/ and move most of these
files there?

It makes sense to me. Yet, there are some of those files that contains
both user-facing and kernel-facing docs at the same place.
Btw, I found the same pattern on *several* other subsystems: when
someone is documenting some feature, it tends to document both kAPI,
uAPI and admin.
Right now, what we did so far on most places were to keep the stuff
together, as splitting them could sometimes be painful.
As we are too close to finish the ReST conversion[1], I would prefer to
first finish it.
Then, do a second pass at files outside the new directories (like
admin-guide), in order to better organize things, eventually splitting
some files into kAPI, uAPI and/or admin-guide.
[1] Looking at next-20200217, after my last doc patches applied on this tree:
https://git.linuxtv.org/mchehab/experimental.git/log/?h=all_docs_merged
excluding (most) false positives, we have now only ~50 text files left to
convert:

It makes sense to me. Yet, there are some of those files that contains
both user-facing and kernel-facing docs at the same place.
Btw, I found the same pattern on *several* other subsystems: when
someone is documenting some feature, it tends to document both kAPI,
uAPI and admin.
Right now, what we did so far on most places were to keep the stuff
together, as splitting them could sometimes be painful.
As we are too close to finish the ReST conversion[1], I would prefer to
first finish it.
Then, do a second pass at files outside the new directories (like
admin-guide), in order to better organize things, eventually splitting
some files into kAPI, uAPI and/or admin-guide.

Ok. So, I guess we can just merge the two tables into one, like:
============ =================
O_RDONLY Shared Read
O_RDWR Exclusive
O_NONBLOCK Trylock operation
============ =================
Right?

Thanks for reviewing it!

From my side, it would be ok if you want to pick any patches from this series.
Still, as they all touch Documentation/filesystems/index.rst, in order
to avoid (trivial) conflicts, IMO the best would be to have all of them
applied at the same tree (either a FS tree or the docs tree).

Mauro

I think they should be in different section.
The first two are lock level, while the last is lock behavior.

Yeah, I also think it makes more sense to just push them through a single
tree - likely docs tree...

Looks fine to me. Mauro, should I merge this via the ceph tree, or are
you merging them in via some other tree? In any case:

I'm looking forward to this phase! Yes it is harder, and it often
requires selling the idea to skeptical maintainers. But that is how,
IMO, we get from where we're at now to something closer to a set of
coherent kernel docs.

I'm looking forward to this phase! Yes it is harder, and it often
requires selling the idea to skeptical maintainers. But that is how,
IMO, we get from where we're at now to something closer to a set of
coherent kernel docs.
Thanks,

Yeah, fully agreed that this is an important step.
I'm even more anxious for a third phase: filling the gaps. I'm pretty sure
that several important parts of the Kernel aren't properly represented
at Documentation.
Yet, before start writing new things, we should first organizing what we
already have, making them well-organized.
Cheers,
Mauro
