X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=10d1459fafbb02a18e7bc8f2c384a9e973560b00;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

dlm: don't limit active work items

Allow multiple workqueue items (locks with callbacks) to be
processed concurrently.  There should be no reason not to
take advantage of this workqueue feature.
