cxl: no need to check return value of debugfs_create functions

2019-06-18T11:40:25+00:00

When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this. Because there's no need to check, also make the return value of the local debugfs_create_io_x64() call void, as no one ever did anything with the return value (as they did not need to.) And make the cxl_debugfs_* calls return void as no one was even checking their return value at all.

vfs: Convert cxl to use the new mount API

2019-05-25T22:06:14+00:00

Convert the cxl filesystem to the new internal mount API as the old one will be obsoleted and removed. This allows greater flexibility in communication of mount parameters between userspace, the VFS and the filesystem. See Documentation/filesystems/mount_api.txt for more information.

mount_pseudo(): drop 'name' argument, switch to d_make_root()

2019-05-25T21:59:24+00:00

Once upon a time we used to set ->d_name of e.g. pipefs root so that d_path() on pipes would work. These days it's completely pointless - dentries of pipes are not even connected to pipefs root. However, mount_pseudo() had set the root dentry name (passed as the second argument) and callers kept inventing names to pass to it. Including those that didn't *have* any non-root dentries to start with... All of that had been pointless for about 8 years now; it's time to get rid of that cargo-culting... Signed-off-by: Al Viro

misc: remove redundant 'default n' from Kconfig-s

2019-05-24T16:00:41+00:00

'default n' is the default value for any bool or tristate Kconfig setting so there is no need to write it explicitly. Also since commit f467c5640c29 ("kconfig: only write '# CONFIG_FOO is not set' for visible symbols") the Kconfig behavior is the same regardless of 'default n' being present or not: ... One side effect of (and the main motivation for) this change is making the following two definitions behave exactly the same: config FOO bool config FOO bool default n With this change, neither of these will generate a '# CONFIG_FOO is not set' line (assuming FOO isn't selected/implied). That might make it clearer to people that a bare 'default n' is redundant. ...
