Hi Adam! * Adam Langley <agl@xxxxxxxxxx>, 2020-04-28, 17:40:
These .I advice values do not influence the semantics of the application (except in the case of -.BR MADV_DONTNEED ), +.BR MADV_DONTNEED +and +.BR MADV_WIPEONFORK ), but may influence its performance.
This sentence is in the "Conventional advice value" subsection, which defines only MADV_NORMAL, MADV_RANDOM, MADV_SEQUENTIAL, MADV_WILLNEED, and MADV_DONTNEED.
MADV_WIPEONFORK is defined in the "Linux-specific advice values" subsection, which already notes that "some of these operations change the semantics of memory accesses". (Perhaps s/some/most/ would be better wording.)
