函数名称：aa_vec_unique - canonical sort and unique a list of profiles*@n: number of refcounted profiles in the list (@n > 0)*@vec: list of profiles to sort and merge* Returns: the number of duplicates eliminated == references put* If @flags & VEC_FLAG_TERMINATE

函数原型：int aa_vec_unique(struct aa_profile **vec, int n, int flags)

返回类型：int

参数：

类型参数名称
struct aa_profile **vec
intn
intflags
264  dups等于0
266  AA_BUG(n < 1)
267  AA_BUG(!vec)
270  如果n大于8则
271  sort(vec, n, *的长度, sort_cmp, NULL)
272  dups等于assumes vec is sorted* Assumes @vec has null terminator at vec[n], and will null terminate* vec[n - dups]
273  转到:out
277  以i小于n循环
278  tmp等于vec[i]
281  以pos大于等于0循环
282  res等于profile_cmp - profile comparison for set ordering*@a: profile to compare (NOT NULL)*@b: profile to compare (NOT NULL)* Returns: <0 if a < b* ==0 if a == b* >0 if a > b
284  如果res恒等于0则
289  否则如果res小于0则退出
293  pos自加
295  以j大于pos循环vec[j]等于vec[j - 1]
297  vec[pos]等于tmp
298  continue_outer :
302  AA_BUG(dups < 0)
304  out :
305  如果flags按位与VEC_FLAG_TERMINATE则vec[n - dups] = NULL
308  返回:dups

aa_label_strn_parseaa_label_strn_parse - parse, validate and convert a text string to a label*@base: base label to use for lookups (NOT NULL)*@str: null terminated text string (NOT NULL)*@n: length of str to parse, will stop at \0 if encountered before n*@gfp: allocation
__label_update__label_update - insert updated version of @label into labelset*@label - the label to update/replace* Returns: new label that is up to date* else NULL on failure* Requires: @ns lock be held* Note: worst case is the stale @label does not get updated and has
