autofs4: move linux/auto_dev-ioctl.h to uapi/linux

2016-10-11T22:06:31+00:00

Since linux/auto_dev-ioctl.h wasn't included in include/linux/Kbuild
it wasn't moved to uapi/linux as part of the uapi series.

autofs: remove AUTOFS_DEVID_LEN

2016-10-11T22:06:31+00:00

This macro was never used by neither kernel nor userspace, and also
doesn't represent "devid length" in bytes.  (unless it was added to mean
something else).

autofs4: fix string.h include in auto_dev-ioctl.h

2016-03-15T23:55:16+00:00

Since including linux/string.h will now do the right thing remove the
conditional check.

autofs4: coding style fixes

2016-03-15T23:55:16+00:00

Try and make the coding style completely consistent throughtout the
autofs module and inline with kernel coding style recommendations.

autofs4: fix kernel includes

2009-04-01T15:59:23+00:00

autofs_dev-ioctl.h is included by both the kernel module and user space tools
and it includes two kernel header files.  Compiles work if the kernel headers
are installed but fail otherwise.

autofs4: improve parameter usage

2009-01-06T23:59:23+00:00

The parameter usage in the device node ioctl code uses arg1 and arg2 as
parameter names.  This patch redefines the parameter names to reflect what
they actually are in an effort to make the code more readable.

autofs4: add miscellaneous device for ioctls

2008-10-16T18:21:39+00:00

Add a miscellaneous device to the autofs4 module for routing ioctls.  This
provides the ability to obtain an ioctl file handle for an autofs mount
point that is possibly covered by another mount.

The actual problem with autofs is that it can't reconnect to existing
mounts.  Immediately one things of just adding the ability to remount
autofs file systems would solve it, but alas, that can't work.  This is
because autofs direct mounts and the implementation of "on demand mount
and expire" of nested mount trees have the file system mounted on top of
the mount trigger dentry.

To resolve this a miscellaneous device node for routing ioctl commands to
these mount points has been implemented in the autofs4 kernel module and a
library added to autofs.  This provides the ability to open a file
descriptor for these over mounted autofs mount points.

Please refer to Documentation/filesystems/autofs4-mount-control.txt for a
discussion of the problem, implementation alternatives considered and a
description of the interface.
