Hi,How do I enable the MAP_SYNC flag in mmap for linux 4.15, my code does not compile with that flag on linux 4.15.0-041500rc7-generic #201801072330
Get your distro to ship an update to /usr/include/linux (kernel-headers) that contains the flag. Your kernel supports it, but your toolchain doesn't until you get an include file that includes the update for MAP_SYNC
Also, how do I make mmap support map size of 2GB or larger, currently the call to mmap fails with mapsize of 2GB.
What error code does it fail with? _______________________________________________ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
