debugfs_create_file_unsafe — create a file in the debugfs filesystem
struct dentry * debugfs_create_file_unsafe ( | const char * name, |
umode_t mode, | |
struct dentry * parent, | |
void * data, | |
const struct file_operations * fops) ; |
const char * name
a pointer to a string containing the name of the file to create.
umode_t mode
the permission that the file should have.
struct dentry * parent
a pointer to the parent dentry for this file. This should be a directory dentry if set. If this parameter is NULL, then the file will be created in the root of the debugfs filesystem.
void * data
a pointer to something that the caller will want to get to later
on. The inode.i_private pointer will point to this value on
the open
call.
const struct file_operations * fops
a pointer to a struct file_operations that should be used for this file.
debugfs_create_file_unsafe
is completely analogous to
debugfs_create_file
, the only difference being that the fops
handed it will not get protected against file removals by the
debugfs core.
It is your responsibility to protect your struct file_operation
methods against file removals by means of debugfs_use_file_start
and debugfs_use_file_finish
. ->open
is still protected by
debugfs though.
Any struct file_operations defined by means of
DEFINE_DEBUGFS_ATTRIBUTE
is protected against file removals and
thus, may be used here.
