2022-03-22T22:57:00Z

inode->i_mutex has been replaced with inode->i_rwsem long ago. Fix comments still mentioning i_mutex.

block: pass a block_device and opf to bio_alloc

2022-02-02T14:49:59Z

Pass the block_device and operation that we plan to use this bio for to bio_alloc to optimize the assignment. NULL/0 can be passed, both for the passthrough case on a raw request_queue and to temporarily avoid refactoring some nasty code. Also move the gfp_mask argument after the nr_vecs argument for a much more logical calling convention matching what most of the kernel does.

Merge tag 'bitmap-5.17-rc1' of git://github.com/norov/linux

2022-01-23T04:20:44Z

2022-01-15T16:47:31Z

find_first{,_zero}_bit is a more effective analogue of 'next' version if start == 0. This patch replaces 'next' with 'first' where things look trivial. Signed-off-by: Yury Norov Tested-by: Wolfram Sang

ocfs2: cluster: use default_groups in kobj_type

2022-01-15T14:30:24Z

There are currently two ways to create a set of sysfs files for a kobj_type, through the default_attrs field, and the default_groups field. Move the ocfs2 cluster sysfs code to use default_groups field which has been the preferred way since aa30f47cf666 ("kobject: Add support for default attribute groups to kobj_type") so that we can soon get rid of the obsolete default_attrs field.

ocfs2: remove redundant initialization of variable ret

The variable ret is being initialized with a value that is never read, the assignment is redundant and can be removed.

ocfs2: replace simple_strtoull() with kstrtoull()

2021-06-29T17:53:46Z

simple_strtoull() is deprecated in some situation since it does not check for the range overflow, use kstrtoull() instead.

treewide: remove editor modelines and cruft

2021-05-07T07:26:34Z

The section "19) Editor modelines and other cruft" in Documentation/process/coding-style.rst clearly says, "Do not include any of these in source files." I recently receive a patch to explicitly add a new one. Let's do treewide cleanups, otherwise some people follow the existing code and attempt to upstream their favoriate editor setups. It is even nicer if scripts/checkpatch.pl can check it. If we like to impose coding style in an editor-independent manner, I think editorconfig (patch [1]) is a saner solution.
