From: Borislav Petkov <[EMAIL PROTECTED]> Teach the debug logging macro to differentiate different log levels based on the type of debug level enabled specifically instead of a threshold-based one. Thus, convert tape->debug_level to a bitmask that is written to over /proc.
Also, - Cleanup and simplify debug macro thus removing a lot of code lines, - Get rid of unused debug levels, - Adjust the loglevel at several places where it was simply missing (e.g. idetape_chrdev_open() etc.) Signed-off-by: Borislav Petkov <[EMAIL PROTECTED]> --- drivers/ide/ide-tape.c | 310 +++++++++++++++++------------------------------- 1 files changed, 107 insertions(+), 203 deletions(-) diff --git a/drivers/ide/ide-tape.c b/drivers/ide/ide-tape.c index efb9d25..a2e7df0 100644 --- a/drivers/ide/ide-tape.c +++ b/drivers/ide/ide-tape.c @@ -103,24 +103,27 @@ typedef struct os_dat_s { #define IDETAPE_MAX_PIPELINE_STAGES 400 #define IDETAPE_INCREASE_STAGES_RATE 20 -/* - * The following are used to debug the driver: - * - * Setting IDETAPE_DEBUG_LOG to 1 will log driver flow control. - * some places. - * - * Setting them to 0 will restore normal operation mode: - * - * 1.
