511 | * _ctx_struct: The context that was passed when creating the debugfs file | |
512 | * | |
513 | * QLA_DFS_SETUP_RD could be used when there is only a show function. | |
514 | * - show function take the name qla_dfs_<sysfs-name>_show | |
515 | * | |
516 | * QLA_DFS_SETUP_RW could be used when there are both show and write functions. | |
517 | * - show function take the name qla_dfs_<sysfs-name>_show | |
518 | * - write function take the name qla_dfs_<sysfs-name>_write | |
519 | * | |
520 | * To have a new debugfs entry, do: | |
521 | * 1. Create a "struct dentry *" in the appropriate structure in the format | |
522 | * dfs_<sysfs-name> | |
523 | * 2. Setup debugfs entries using QLA_DFS_SETUP_RD / QLA_DFS_SETUP_RW | |
524 | * 3. Create debugfs file in qla2x00_dfs_setup() using QLA_DFS_CREATE_FILE | |
525 | * or QLA_DFS_ROOT_CREATE_FILE | |
526 | * 4. Remove debugfs file in qla2x00_dfs_remove() using QLA_DFS_REMOVE_FILE | |
527 | * or QLA_DFS_ROOT_REMOVE_FILE | |
528 | * | |
529 | * Example for creating "TEST" sysfs file: | |
530 | * 1. struct qla_hw_data { ... struct dentry *dfs_TEST; } | |
531 | * 2. QLA_DFS_SETUP_RD(TEST, scsi_qla_host_t); | |
