      Detach sched.h from mm.h · e8edc6e0
      Alexey Dobriyan authored
      
      
      First thing mm.h does is including sched.h solely for can_do_mlock() inline
      function which has "current" dereference inside. By dealing with can_do_mlock()
      mm.h can be detached from sched.h which is good. See below, why.
      
      This patch
      a) removes unconditional inclusion of sched.h from mm.h
      b) makes can_do_mlock() normal function in mm/mlock.c
      c) exports can_do_mlock() to not break compilation
      d) adds sched.h inclusions back to files that were getting it indirectly.
      e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were
         getting them indirectly
      
      Net result is:
      a) mm.h users would get less code to open, read, preprocess, parse, ... if
         they don't need sched.h
      b) sched.h stops being dependency for significant number of files:
         on x86_64 allmodconfig touching sched.h results in recompile of 4083 files,
         after patch it's only 3744 (-8.3%).
      
      Cross-compile tested on
      
      	all arm defconfigs, all mips defconfigs, all powerpc defconfigs,
      	alpha alpha-up
      	arm
      	i386 i386-up i386-defconfig i386-allnoconfig
      	ia64 ia64-up
      	m68k
      	mips
      	parisc parisc-up
      	powerpc powerpc-up
      	s390 s390-up
      	sparc sparc-up
      	sparc64 sparc64-up
      	um-x86_64
      	x86_64 x86_64-up x86_64-defconfig x86_64-allnoconfig
      
      as well as my two usual configs.

      9p: implement optional loose read cache · e03abc0c
      Eric Van Hensbergen authored
      
      
      While cacheing is generally frowned upon in the 9p world, it has its
      place -- particularly in situations where the remote file system is
      exclusive and/or read-only.  The vacfs views of venti content addressable
      store are a real-world instance of such a situation.  To facilitate higher
      performance for these workloads (and eventually use the fscache patches),
      we have enabled a "loose" cache mode which does not attempt to maintain
      any form of consistency on the page-cache or dcache.  This results in over
      two orders of magnitude performance improvement for cacheable block reads
      in the Bonnie benchmark.  The more aggressive use of the dcache also seems
      to improve metadata operational performance.
