      procfs: new helper - PDE_DATA(inode) · d9dda78b
      Al Viro 提交于
      The only part of proc_dir_entry the code outside of fs/proc
      really cares about is PDE(inode)->data.  Provide a helper
      for that; static inline for now, eventually will be moved
      to fs/proc, along with the knowledge of struct proc_dir_entry
      layout.

      wireless: drivers: make use of WLAN_EID_VENDOR_SPECIFIC · 04b2312a
      Arend van Spriel 提交于
      The include file linux/ieee80211.h contains three definitions for
      the same thing in enum ieee80211_eid due to historic changes:
      
      /* Information Element IDs */
      enum ieee80211_eid {
          :
          WLAN_EID_WPA = 221,
          WLAN_EID_GENERIC = 221,
          WLAN_EID_VENDOR_SPECIFIC = 221,
          :
      };
      
      The standard refers to this as "vendor specific" element so the
      other two definitions are better not used. This patch changes the
      wireless drivers to use one definition, ie. WLAN_EID_VENDOR_SPECIFIC.

      wireless: Remove casts to same type · 2c208890
      Joe Perches 提交于
      Adding casts of objects to the same type is unnecessary
      and confusing for a human reader.
      
      For example, this cast:
      
              int y;
              int *p = (int *)&y;
      
      I used the coccinelle script below to find and remove these
      unnecessary casts.  I manually removed the conversions this
      script produces of casts with __force, __iomem and __user.
      
      @@
      type T;
      T *p;

      Neatened the mwifiex_deauthenticate_infra function which
      was doing odd things with array pointers and not using
      is_zero_ether_addr.

      net: Audit drivers to identify those needing IFF_TX_SKB_SHARING cleared · 550fd08c
      Neil Horman 提交于
      After the last patch, We are left in a state in which only drivers calling
      ether_setup have IFF_TX_SKB_SHARING set (we assume that drivers touching real
      hardware call ether_setup for their net_devices and don't hold any state in
      their skbs.  There are a handful of drivers that violate this assumption of
      course, and need to be fixed up.  This patch identifies those drivers, and marks
      them as not being able to support the safe transmission of skbs by clearning the
      IFF_TX_SKB_SHARING flag in priv_flags

      llseek: automatically add .llseek fop · 6038f373
      Arnd Bergmann 提交于
      All file_operations should get a .llseek operation so we can make
      nonseekable_open the default for future file operations without a
      .llseek pointer.
      
      The three cases that we can automatically detect are no_llseek, seq_lseek
      and default_llseek. For cases where we can we can automatically prove that
      the file offset is always ignored, we use noop_llseek, which maintains
      the current behavior of not returning an error from a seek.
      
      New drivers should normally not use noop_llseek but instead use no_llseek
      and call nonseekable_open at open time.  Existing drivers can be converted
      to do the same when the maintainer knows for certain that no user code
      relies on calling seek on the device file.
      
      The generated code is often incorrectly indented and right now contains
      comments that clarify for each added line why a specific variant was
      chosen. In the version that gets submitted upstream, the comments will
      be gone and I will manually fix the indentation, because there does not
      seem to be a way to do that using coccinelle.
      
      Some amount of new code is currently sitting in linux-next that should get
      the same modifications, which I will do at the end of the merge window.
      
      Many thanks to Julia Lawall for helping me learn to write a semantic
      patch that does all this.
