This\nstems from the problem of passing a userspace buffer into read() or write() on\nthe host. If that buffer had not yet been faulted in, read and write will\nreturn -EFAULT.\n\nTo avoid this problem, the solution was to fault the buffer in before the\nsystem call by touching the pages that hold the buffer by doing a copy-user of\na byte to each page. This is obviously bogus, but it does usually work, in tt\nmode, since the kernel and process are in the same address space and userspace\naddresses can be accessed directly in the kernel.\n\nIn skas mode, where the kernel and process are in separate address spaces, it\nis completely bogus because the userspace address, which is invalid in the\nkernel, is passed into the system call instead of the corresponding physical\naddress, which would be valid. Here, it appears that this code, on every host\nread() or write(), tries to fault in a random process page. This doesn\u0027t seem\nto cause any correctness problems, but there is a performance impact. This\npatch, and the ones following, result in a 10-15% performance gain on a kernel\nbuild.\n\nThis code can\u0027t be immediately tossed out because when it is, you can\u0027t log\nin. Apparently, there is some code in the console driver which depends on\nthis somehow.\n\nHowever, we can start removing it by switching the code which does I/O using\nkernel addresses to using plain read() and write(). This patch introduces\nos_read_file_k and os_write_file_k for use with kernel buffers and converts\nall call locations which use obvious kernel buffers to use them. These\ninclude I/O using buffers which are local variables which are on the stack or\nkmalloc-ed.
