[PATCH net-next v2] net: tso: inline tso_count_descs()
by Yunsheng Lin 13 Dec '22

13 Dec '22

tso_count_descs() is a small function doing simple calculation, and tso_count_descs() is used in fast path, so inline it to reduce the overhead of calls.

[PATCH v3 0/5] add debugfs to migration driver
by Longfang Liu 01 Dec '22

01 Dec '22

Add a debugfs function to the migration driver in VFIO to provide a step-by-step test function for the migration driver. When the execution of live migration fails, the user can view the status and data during the migration process separately from the source and the destination, which is convenient for users to analyze and locate problems. Changes v2 -> v3 Extend the debugfs function from hisilicon device to vfio. Changes v1 -> v2 Change the registration method of root_debugfs to register with module initialization.
