      sh: Fix boot crash related to SCI · fc97114b
      Rafael J. Wysocki authored
      Commit d006199e72a9 ("serial: sh-sci: Regtype probing doesn't need to be
      fatal.") made sci_init_single() return when sci_probe_regmap() succeeds,
      although it should return when sci_probe_regmap() fails.  This causes
      systems using the serial sh-sci driver to crash during boot.
      
      Fix the problem by using the right return condition.

      arm: remove "optimized" SHA1 routines · 4d448714
      Linus Torvalds authored
      Since commit 1eb19a12 ("lib/sha1: use the git implementation of
      SHA-1"), the ARM SHA1 routines no longer work.  The reason? They
      depended on the larger 320-byte workspace, and now the sha1 workspace is
      just 16 words (64 bytes).  So the assembly version would overwrite the
      stack randomly.
      
      The optimized asm version is also probably slower than the new improved
      C version, so there's no reason to keep it around.  At least that was
      the case in git, where what appears to be the same assembly language
      version was removed two years ago because the optimized C BLK_SHA1 code
      was faster.

      vfs: optimize inode cache access patterns · 3ddcd056
      Linus Torvalds authored
      The inode structure layout is largely random, and some of the vfs paths
      really do care.  The path lookup in particular is already quite D$
      intensive, and profiles show that accessing the 'inode->i_op->xyz'
      fields is quite costly.
      
      We already optimized the dcache to not unnecessarily load the d_op
      structure for members that are often NULL using the DCACHE_OP_xyz bits
      in dentry->d_flags, and this does something very similar for the inode
      ops that are used during pathname lookup.
      
      It also re-orders the fields so that the fields accessed by 'stat' are
      together at the beginning of the inode structure, and roughly in the
      order accessed.
      
      The effect of this seems to be in the 1-2% range for an empty kernel
      "make -j" run (which is fairly kernel-intensive, mostly in filename
      lookup), so it's visible.  The numbers are fairly noisy, though, and
      likely depend a lot on exact microarchitecture.  So there's more tuning
      to be done.

      tree.

      exofs: Rename raid engine from exofs/ios.c => ore · 8ff660ab
      Boaz Harrosh authored
      ORE stands for "Objects Raid Engine"
      
      This patch is a mechanical rename of everything that was in ios.c
      and its API declaration to an ore.c and an osd_ore.h header. The ore
      engine will later be used by the pnfs objects layout driver.
      
      * File ios.c => ore.c
      
      * Declaration of types and API are moved from exofs.h to a new
        osd_ore.h
      
      * All used types are prefixed by ore_ from their exofs_ name.
      
      * Shift includes from exofs.h to osd_ore.h so osd_ore.h is
        independent, include it from exofs.h.
      
      Other than a pure rename there are no other changes. Next patch
      will move the ore into it's own module and will export the API
      to be used by exofs and later the layout driver

      exofs: ios: Move to a per inode components & device-table · 9e9db456
      Boaz Harrosh authored
      Exofs raid engine was saving on memory space by having a single layout-info,
      single pid, and a single device-table, global to the filesystem. Then passing
      a credential and object_id info at the io_state level, private for each
      inode. It would also devise this contraption of rotating the device table
      view for each inode->ino to spread out the device usage.
      
      This is not compatible with the pnfs-objects standard, demanding that
      each inode can have it's own layout-info, device-table, and each object
      component it's own pid, oid and creds.
      
      So: Bring exofs raid engine to be usable for generic pnfs-objects use by:
      
      * Define an exofs_comp structure that holds obj_id and credential info.
      
      * Break up exofs_layout struct to an exofs_components structure that holds a
        possible array of exofs_comp and the array of devices + the size of the
        arrays.
      
      * Add a "comps" parameter to get_io_state() that specifies the ids creds
        and device array to use for each IO.
      
        This enables to keep the layout global, but the device-table view, creds
        and IDs at the inode level. It only adds two 64bit to each inode, since
        some of these members already existed in another form.
      
      * ios raid engine now access layout-info and comps-info through the passed
        pointers. Everything is pre-prepared by caller for generic access of
        these structures and arrays.
      
      At the exofs Level:
      
      * Super block holds an exofs_components struct that holds the device
        array, previously in layout. The devices there are in device-table
        order. The device-array is twice bigger and repeats the device-table
        twice so now each inode's device array can point to a random device
        and have a round-robin view of the table, making it compatible to
        previous exofs versions.
      
      * Each inode has an exofs_components struct that is initialized at
        load time, with it's own view of the device table IDs and creds.
        When doing IO this gets passed to the io_state together with the
        layout.
      
      While preforming this change. Bugs where found where credentials with the
      wrong IDs where used to access the different SB objects (super.c). As well
      as some dead code. It was never noticed because the target we use does not
      check the credentials.
