| H A D | target_core_sbc.c | cf6d1f09 Wed Aug 21 21:34:43 CDT 2013 Nicholas Bellinger <nab@daterainc.com> target: Release COMPARE_AND_WRITE mutex in generic failure path
This patch adds a extra check for SCF_COMPARE_AND_WRITE within
transport_generic_request_failure() to invoke the callback for
compare_and_write_callback() or compare_and_write_done(), in
order to release se_dev->caw_mutex from the generic failure
path.
It also adds to checks within compare_and_write_callback() to
avoid processing when transport_generic_request_failure() occurs
early enough that cmd->t_data_sg or cmd->t_bidi_data_sg have not
been setup yet, nor se_dev->caw_mutex obtained from within
sbc_compare_and_write().
v4 changes:
- Add explicit check for cmd->transport_complete_callback in
transport_generic_request_failure() to handle case where
sbc_compare_and_write()clears callback pointer (Dan Carpenter)
