Remarks:
-
 
3128
  * The function is used only in the application 'systrace'.
-
 
3129
    It is rather difficult to imagine a situation, in which
-
 
3130
    this application or this function are really useful;
-
 
3131
    and all system calls for support of this function are a little
-
 
3132
    decelerated (though not strongly)...
-
 
3133
  * So there is a proposition to delete from the kernel
-
 
3134
    support of this function, together with application 'systrace'.
-
 
3135
  * The information on system calls saves in the system
-
 
3136
    ring buffer with 0x10 entries.
-
 
3137
    This function simply copies the given size of data
-
 
3138
    from this buffer to the given address.
-
 
3139
  * One can determine, which entry in the buffer corresponds to
-
 
3140
    last system call, by value of eax, namely, it is the entry
-
 
3141
    (eax and 0xF) (at offset (eax and 0xF)*0x40).
-
 
3142
  * In the current implementation there can be the seldom
-
 
3143
    meeting problems of unsynchronization, when the information
-
 
3144
    on some calls becomes outdated.
-
 
3145
  * Under the system buffer one page, 4Kb, is allocated.
-
 
3146
    Size of an entry = 64 bytes. Why only 16 entries are used,
-
 
3147
    is not clearly.
-
 
3148
  * The value of esp at the moment of system call cannot
-
 
3149
    be determined by this function.
-
 
3150
  * The current implementation does not check edx for correctness.
