      i2c-omap: fix static suspend vs. runtime suspend · adf6e079
      Kevin Hilman authored
      When runtime PM is enabled, each OMAP i2c device is suspended after
      each i2c xfer.  However, there are two cases when the static suspend
      methods must be used to ensure the devices are suspended:
      
      1) runtime PM is disabled, either at compile time or dynamically
          via /sys/devices/.../power/control.
      2) an i2c client driver uses i2c during it's suspend callback, thus
         leaving the i2c driver active (NOTE: runtime suspend transitions are
         disabled during system suspend, so i2c activity during system
         suspend will runtime resume the device, but not runtime (re)suspend it.)
      
      Since the actual work to suspend the device is handled by the
      subsytem, call the bus methods to take care of it.
      
      NOTE: This takes care of a known suspend problem on OMAP3 where the
      TWL RTC driver does i2c xfers during its suspend path leaving the i2c
      driver in an active state (since runtime suspend transistions are
      disabled.)

      xfs: check if device support discard in xfs_ioc_trim() · be715140
      Lukas Czerner authored
      Right now we, are relying on the fact that when we attempt to
      actually do the discard, blkdev_issue_discar() returns -EOPNOTSUPP
      and the user is informed that the device does not support discard.
      
      However, in the case where the we do not hit any suitable free
      extent to trim in FITRIM code, it will finish without any error.
      This is very confusing, because it seems that FITRIM was successful
      even though the device does not actually supports discard.
      
      Solution: Check for the discard support before attempt to search for
      free extents.

      xfs: prevent leaking uninitialized stack memory in FSGEOMETRY_V1 · 3a3675b7
      Dan Rosenberg authored
      The FSGEOMETRY_V1 ioctl (and its compat equivalent) calls out to
      xfs_fs_geometry() with a version number of 3.  This code path does not
      fill in the logsunit member of the passed xfs_fsop_geom_t, leading to
      the leaking of four bytes of uninitialized stack data to potentially
      unprivileged callers.
      
      v2 switches to memset() to avoid future issues if structure members
      change, on suggestion of Dave Chinner.
