* Helper macros for setting up debugfs entries.
|
|
* _name: The name of the debugfs entry
|
|
* _ctx_struct: The context that was passed when creating the debugfs file
|
|
*
|
|
* QLA_DFS_SETUP_RD could be used when there is only a show function.
|
|
* - show function take the name qla_dfs_<sysfs-name>_show
|
|
*
|
|
* QLA_DFS_SETUP_RW could be used when there are both show and write functions.
|
|
* - show function take the name qla_dfs_<sysfs-name>_show
|
|
* - write function take the name qla_dfs_<sysfs-name>_write
|
|
*
|
|
* To have a new debugfs entry, do:
|
|
* 1. Create a "struct dentry *" in the appropriate structure in the format
|
|
* dfs_<sysfs-name>
|
|
* 2. Setup debugfs entries using QLA_DFS_SETUP_RD / QLA_DFS_SETUP_RW
|
|
* 3. Create debugfs file in qla2x00_dfs_setup() using QLA_DFS_CREATE_FILE
|
|
* or QLA_DFS_ROOT_CREATE_FILE
|
|
* 4. Remove debugfs file in qla2x00_dfs_remove() using QLA_DFS_REMOVE_FILE
|
|
* or QLA_DFS_ROOT_REMOVE_FILE
|
|
*
|
|
* Example for creating "TEST" sysfs file:
|
|
* 1. struct qla_hw_data { ... struct dentry *dfs_TEST; }
|
|
* 2. QLA_DFS_SETUP_RD(TEST, scsi_qla_host_t);
|
|
* 3. In qla2x00_dfs_setup():
|
|
* QLA_DFS_CREATE_FILE(ha, TEST, 0600, ha->dfs_dir, vha);
|
|
* 4. In qla2x00_dfs_remove():
|
|
* QLA_DFS_REMOVE_FILE(ha, TEST);
