[PATCH 1/3] workqueue: Convert for_each_wq to use built-in list check (v2)

list_for_each_entry_rcu now has support to check for RCU reader sections as well as lock. Just use the support in it, instead of explicitly checking in the caller. Signed-off-by: Joel Fernandes (Google) --- kernel/workqueue.c | 10 ++ 1 file changed, 2 insertions(+), 8 deletions(-) diff

[PATCH 3/3] driver/core: Fix build error when SRCU and lockdep disabled

Properly check if lockdep lock checking is disabled at config time. If so, then lock_is_held() is undefined so don't do any checking. This fix is similar to the pattern used in srcu_read_lock_held(). Link: https://lore.kernel.org/lkml/201908080026.wsafx14k%25...@intel.com/ Fixes: c9e4d3a2fee8 ("a

[PATCH v5 0/9] FPGA DFL updates

Hi Greg, This is v5 patchset which adds more features to FPGA DFL. Marjor changes against v4 are sysfs related code rework to address comments on v4. Please help to take a look. Thanks! Main changes from v4: - convert code to use dev_groups for sysfs entries (#2, #3, #4, #6, #8). - clean up

[PATCH v5 4/9] fpga: dfl: afu: add userclock sysfs interfaces.

This patch introduces userclock sysfs interfaces for AFU, user could use these interfaces for clock setting to AFU. Please note that, this is only working for port header feature with revision 0, for later revisions, userclock setting is moved to a separated private feature, so one revision sysfs
