  • 064223c12   dca: make function dca_common_get_tag static ... Browse Code »

    Function dca_common_get_tag is local to the source and does not need to be
    in global scope, so make it static.

    Cleans up sparse warning:
    drivers/dca/dca-core.c:273:4: warning: symbol 'dca_common_get_tag' was
    not declared. Should it be static?

  • a1741e7fc   locking, drivers/dca: Annotate dca_lock as raw ... Browse Code »

    The dca_lock can be taken in atomic context:

    and thus must not be preempted on -rt.

    In mainline this change documents the low level nature of
    the lock - otherwise there's no functional difference. Lockdep
    and Sparse checking will work as usual.

  • f0f2c2b5b   dca: remove unneeded NULL check ... Browse Code »

    The return here doesn't release the locks or re-enable IRQs. But as
    Andrew Morton points out, domain is never NULL. list_first_entry()
    essentially never returns NULL and also we already verified that the list
    is not empty.
