      ext[34]: avoid i_nlink warnings triggered by drop_nlink/inc_nlink kludge in symlink() · 0ce8c010
      Al Viro authored
      Both ext3 and ext4 put the half-created symlink inode into the orphan list
      for a while (see the comment in ext[34]_symlink() for gory details).  Then,
      if everything went fine, they pull it out of the orphan list and bump the
      link count back to 1.  The thing is, inc_nlink() is going to complain about
      seeing somebody changing i_nlink from 0 to 1.  With a good reason, since
      normally something like that is a bug.  Explicit set_nlink(inode, 1) does
      the same thing as inc_nlink() here, but it does *not* complain - exactly
      because it should be usable in strange situations like this one.

      * if you do dput() of root dentry, do *not* follow that with iput() of root
      inode.
      * while we are at it, don't do that dput() at all - you are leaving the pointer
      in ->s_root and your ->kill_sb() will be very unhappy with that.  It will do
      proper dput(), though, so the easiest way is to leave that to it entirely.
      * freeing ->s_fs_info is also best left to ->kill_sb() (which will do it
      anyway), especially since we leave the pointer in place.
      * that xchg() in ->kill_sb() is not a bug per se, but it's a plain and simple
      masturbation with fewer excuses than Onan had...

      audit: always follow va_copy() with va_end() · a0e86bd4
      Jesper Juhl authored
      A call to va_copy() should always be followed by a call to va_end() in
      the same function.  In kernel/autit.c::audit_log_vformat() this is not
      always done.  This patch makes sure va_end() is always called.

      drivers/scsi/aacraid/commctrl.c: fix mem leak in aac_send_raw_srb() · 7dd72f51

      			goto cleanup;
      	... this 'goto' makes 'usg' go out of scope and leak the memory we
      	    allocated.
      
      Other exits properly kfree(usg), it's just here it is neglected.
