   7 ** LOGGING
   8 **
   9 ** - Avoid SHOUTING needlessly. Avoid excessive verbosity.
  10 **   Gradually remove messages which are old debugging aids.
  11 **
  12 ** - Use printk() for messages which are to be always logged.
  13 **   Supply either 'acx:' or '<devname>:' prefix so that user
  14 **   can figure out who's speaking among other kernel chatter.
  15 **   acx: is for general issues (e.g. "acx: no firmware image!")
  16 **   while <devname>: is related to a particular device
  17 **   (think about multi-card setup). Double check that message
  18 **   is not confusing to the average user.
  19 **
  20 ** - use printk KERN_xxx level only if message is not a WARNING
  21 **   but is INFO, ERR etc.
  22 **
  23 ** - Use printk_ratelimited() for messages which may flood
  24 **   (e.g. "rx DUP pkt!").
  25 **
  26 ** - Use log() for messages which may be omitted (and they
  27 **   _will_ be omitted in non-debug builds). Note that
  28 **   message levels may be disabled at compile-time selectively,
  29 **   thus select them wisely. Example: L_DEBUG is the lowest
  30 **   (most likely to be compiled out) -> use for less important stuff.
  31 **
  32 ** - Do not print important stuff with log(), or else people
  33 **   will never build non-debug driver.
  34 **
  35 ** Style:
  36 ** hex: capital letters, zero filled (e.g. 0x02AC)
  37 ** str: dont start from capitals, no trailing periods ("tx: queue is stopped")

 223 ** LOCKING
 224 ** We have adev->sem and adev->lock.
 225 **
 226 ** We employ following naming convention in order to get locking right:
 227 **
 228 ** acx_e_xxxx - external entry points called from process context.
 229 **      It is okay to sleep. adev->sem is to be taken on entry.
 230 ** acx_i_xxxx - external entry points possibly called from atomic context.
 231 **      Sleeping is not allowed (and thus down(sem) is not legal!)
 232 ** acx_s_xxxx - potentially sleeping functions. Do not ever call under lock!
 233 ** acx_l_xxxx - functions which expect lock to be already taken.
 234 ** rest       - non-sleeping functions which do not require locking
 235 **              but may be run under lock
 236 **
 237 ** A small number of local helpers do not have acx_[eisl]_ prefix.
 238 ** They are always close to caller and are to be reviewed locally.
 239 **
 240 ** Theory of operation:
 241 **
 242 ** All process-context entry points (_e_ functions) take sem
 243 ** immediately. IRQ handler and other 'atomic-context' entry points
 244 ** (_i_ functions) take lock immediately on entry, but dont take sem
 245 ** because that might sleep.
 246 **
 247 ** Thus *all* code is either protected by sem or lock, or both.
 248 **
 249 ** Code which must not run concurrently with IRQ takes lock.
 250 ** Such code is marked with _l_.
 251 **
 252 ** This results in the following rules of thumb useful in code review:
 253 **
 254 ** + If a function calls _s_ fn, it must be an _s_ itself.
 255 ** + You can call _l_ fn only (a) from another _l_ fn
 256 **   or (b) from _s_, _e_ or _i_ fn by taking lock, calling _l_,
 257 **   and dropping lock.
 258 ** + All IRQ code runs under lock.
 259 ** + Any _s_ fn is running under sem.
 260 ** + Code under sem can race only with IRQ code.
 261 ** + Code under sem+lock cannot race with anything.
