Sample text

Therefore, once you’ve made a couple of passes over your code, it’s a good idea to have someone else take a look as well. Since they’re operating from a different frame of reference, they’ll see problems that you continue to miss. Do keep in mind, however, that you shouldn’t waste another engineer’s time; it’s important that you review your own code first and eliminate all the "low lying fruit" before taking up someone else’s time in a review process. Remember, when someone else is reviewing your code, you’re consuming two man hours for each real hour since two of you are participating in the review.

XXXX values. " We’ll discuss this possibility in a later chapter when we discuss blocking I/O. Note that it’s quite possible for the file position to be beyond the end of the device’s data in the data buffer. This can occur, for example, if the user calls the llseek function and advances the file pointer beyond the end of the data. It can also occur if a process is reading data from the device file and another process opens the file as a write-only device, thus resetting the scull_dev len field to zero.

Sem )) then // // // // down_interruptible returns 0 on success, a negative error code on failure (which leads us to this point). Failure means the scullc_dev object is currently being used so we have to wait for it to be free. erestartsys, eax ); exit scullc_write; endif; begin nothing; // If the count was zero, immediately return. mov( 0, rtnVal ); exitif( count = 0 ) nothing; // // // // // // // // 64-bit comparison of f_pos with filp->size. Exit if the file position is greater than the size.
