linux-next: manual merge of the jc_docs tree with the f2fs tree

[Stephen Rothwell]

Hi all,

Today's linux-next merge of the jc_docs tree got a conflict in:

  Documentation/filesystems/f2fs.rst

between commit:

  a7c77c387b60 ("f2fs: fix to document reserved special compression extension")

from the f2fs tree and commit:

  9aa1ccb4e588 ("docs: f2fs: fix a broken table")

from the jc_docs tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

Cheers,
Stephen Rothwell

-                        idle. If background_gc=on, it will turn on the garbage

-                        will be turned off. If background_gc=sync, it will turn
-                        on synchronous garbage collection running in background.
-                        Default value for this option is on. So garbage
-                        collection is on by default.
- disable_roll_forward   Disable the roll-forward recovery routine
- norecovery             Disable the roll-forward recovery routine, mounted read-
-                        only (i.e., -o ro,disable_roll_forward)
- discard/nodiscard      Enable/disable real-time discard in f2fs, if discard is
-                        enabled, f2fs will issue discard/TRIM commands when a
- 		       segment is cleaned.
- no_heap                Disable heap-style segment allocation which finds free
-                        segments for data from the beginning of main area, while
- 		       for node from the end of main area.
- nouser_xattr           Disable Extended User Attributes. Note: xattr is enabled
-                        by default if CONFIG_F2FS_FS_XATTR is selected.
- noacl                  Disable POSIX Access Control List. Note: acl is enabled
-                        by default if CONFIG_F2FS_FS_POSIX_ACL is selected.
- active_logs=%u         Support configuring the number of active logs. In the
-                        current design, f2fs supports only 2, 4, and 6 logs.
-                        Default number is 6.
- disable_ext_identify   Disable the extension list configured by mkfs, so f2fs
-                        does not aware of cold files such as media files.
- inline_xattr           Enable the inline xattrs feature.
- noinline_xattr         Disable the inline xattrs feature.
- inline_xattr_size=%u   Support configuring inline xattr size, it depends on

- inline_data            Enable the inline data feature: New created small(<~3.4k)
-                        files can be written into inode block.
- inline_dentry          Enable the inline dir feature: data in new created

- noinline_dentry        Disable the inline dentry feature.
- flush_merge	       Merge concurrent cache_flush commands as much as possible
-                        to eliminate redundant command issues. If the underlying
- 		       device handles the cache_flush command relatively slowly,
- 		       recommend to enable this option.
- nobarrier              This option can be used if underlying storage guarantees
-                        its cached data should be written to the novolatile area.
- 		       If this option is set, no cache_flush commands are issued
- 		       but f2fs still guarantees the write ordering of all the
- 		       data writes.
- fastboot               This option is used when a system wants to reduce mount
-                        time as much as possible, even though normal performance
- 		       can be sacrificed.
- extent_cache           Enable an extent cache based on rb-tree, it can cache

-                        increasing the cache hit ratio. Set by default.
- noextent_cache         Disable an extent cache based on rb-tree explicitly, see

- noinline_data          Disable the inline data feature, inline data feature is

- reserve_root=%d        Support configuring reserved space which is used for

- checkpoint=%s[:%u[%]]  Set to "disable" to turn off checkpointing. Set to "enable"
-                        to reenable checkpointing. Is enabled by default. While
-                        disabled, any unmounting or unexpected shutdowns will cause

-                        While mounting with checkpoint=disabled, the filesystem must

- compress_log_size=%u   Support configuring compress cluster size, the size will

-                        default size.
- compress_extension=%s  Support adding specified extension, so that f2fs can enable
-                        compression on those corresponding files, e.g. if all files
-                        with '.ext' has high compression rate, we can set the '.ext'
-                        on compression extension list and enable compression on
-                        these file by default rather than to enable it via ioctl.
-                        For other files, we can still enable compression via ioctl.
-                        Note that, there is one reserved special extension '*', it

+ 			 "lz4", "zstd" and "lzo-rle" algorithm.
+ compress_log_size=%u	 Support configuring compress cluster size, the size will
+ 			 be 4KB * (1 << %u), 16KB is minimum size, also it's
+ 			 default size.
+ compress_extension=%s	 Support adding specified extension, so that f2fs can enable
+ 			 compression on those corresponding files, e.g. if all files
+ 			 with '.ext' has high compression rate, we can set the '.ext'
+ 			 on compression extension list and enable compression on
+ 			 these file by default rather than to enable it via ioctl.
+ 			 For other files, we can still enable compression via ioctl.
++			 Note that, there is one reserved special extension '*', it
++			 can be set to enable compression for all files.
