sysfs.txt: mention that store method buffers are null-terminated

2015-09-13T20:38:51+00:00

Without knowing this, the use of sysfs_streq() becomes puzzling.

The termination happens in kernfs_fop_write().

sysfs.txt: fix pre-kernfs sysfs_dirent reference

2015-09-13T20:38:50+00:00

sysfs_dirent went away when kernfs was extracted from sysfs. The reference
to the kobject now lives in a kernfs_node (in the 'priv' member).

See commit 324a56e16e44 ("kernfs: s/sysfs_dirent/kernfs_node/ and rename
its friends accordingly").

sysfs.txt: update show method notes about sprintf/snprintf/scnprintf usage

2015-08-05T22:13:21+00:00

Changed the documentation to allow sprintf() when the buffer
provided by sysfs cannot be overflowed. Explicitly say
snprintf() must never be used in a show function to format
data to be returned to user space.

Change based on a discussion about the patch

docs/sysfs: Specify ABI documentation requirements

2011-08-23T00:42:34+00:00

Although it is expected nowadays that every new sysfs attribute is
documented under Documentation/ABI, this is not yet mentioned in the
kernel documentation. This patch adds a note in the sysfs
documentation about that requirement.

docs/sysfs: show() methods should use scnprintf().

2011-02-03T23:10:18+00:00

Since snprintf() may return a value that exceeds its second argument,
show() methods should use scnprintf() instead of snprintf(). This patch
updates the example in the sysfs documentation accordingly.

docs/sysfs: Update directory/kobject documentation.

2011-02-03T23:10:18+00:00

Some time ago the way how sysfs stores a pointer to a kobject
corresponding to a directory was modified. This patch brings the
documentation again in sync with the implementation.
