      target: Fall back to vzalloc upon ->sess_cmd_map kzalloc failure · 8c7f6e9b
      Nicholas Bellinger authored
      This patch changes transport_alloc_session_tags() to fall back to
      use vzalloc when kzalloc fails for big tag_num that end up generating
      larger order allocations.
      
      Also use is_vmalloc_addr() in transport_alloc_session_tags() failure
      path, and normal transport_free_session() path to determine when
      vfree() needs to be called instead of kfree().
      
      v2 changes:
        - Use  __GFP_NOWARN | __GFP_REPEAT for sess_cmd_map kzalloc (mst)

      vhost/scsi: Use GFP_ATOMIC with percpu_ida_alloc for obtaining tag · 4a47d3a1
      Nicholas Bellinger authored
      Fix GFP_KERNEL -> GFP_ATOMIC usage of percpu_ida_alloc() within
      vhost_scsi_get_tag(), as this code is expected to be called directly
      from interrupt context.
      
      v2 changes:
      
        - Handle possible tag < 0 failure with GFP_ATOMIC

      ib_srpt: Destroy cm_id before destroying QP. · 0b41d6ca
      Nicholas Bellinger authored
      This patch fixes a bug where ib_destroy_cm_id() was incorrectly being called
      after srpt_destroy_ch_ib() had destroyed the active QP.
      
      This would result in the following failed SRP_LOGIN_REQ messages:

      This reverts commit de95ab53.
      
      Markus Trippelsdorf reported that this commit broke 'perf top':
      
       > I just see a gray screen with no text at all. Sometimes the
       > following error messages are printed:
       >
       >  *** Error in `perf': invalid fastbin entry (free): 0x00000000029b18c0
       >  ***
       >  *** Error in `perf': malloc(): memory corruption (fast): 0x0000000000ee0b10 ***
      
      While this code is fixable, the commit itself fails on several levels:
      
       - it should have been a separate helper function
       - why the heck does it do strchr() twice
       - it casts a const char * over into char *
       - sloppy style
       - it's not even a regression fix!
      
      So lets revert it and re-try the patch in v3.13.
