Idan Horowitz	5f95a1a7b7	LibC: Define the MADV_DONTNEED madvise advice macro ... This isn't actually implemented at the moment, but it is required for wine to compile	2021-12-01 21:44:11 +02:00
Idan Horowitz	fc13d0782f	LibC: Make the madvise advice field a value instead of a bitfield ... The advices are almost always exclusive of one another, and while POSIX does not define madvise, most other unix-like and *BSD systems also only accept a singular value per call.	2021-12-01 21:44:11 +02:00
Andreas Kling	32aa37d5dc	Kernel+LibC: Add msync() system call ... This allows userspace to trigger a full (FIXME) flush of a shared file mapping to disk. We iterate over all the mapped pages in the VMObject and write them out to the underlying inode, one by one. This is rather naive, and there's lots of room for improvement. Note that shared file mappings are currently not possible since mmap() returns ENOTSUP for PROT_WRITE+MAP_SHARED. That restriction will be removed in a subsequent commit. :^)	2021-11-17 19:34:15 +01:00
