drivers/net/ethernet/chelsio/inline_crypto/ch_ktls/chcr_ktls.c:1592:22-32: ERROR: function chcr_end_part_handler called on line 1885 inside lock on line 1822 but uses GFP_KERNEL

 Find functions that refer to GFP_KERNEL but are called with locks held.

Semantic patch information:
 The proposed change of converting the GFP_KERNEL is not necessarily the
 correct one.  It may be desired to unlock the lock, or to not call the
 function under the lock in the first place.

Hello,

Please check on this.  Normally, it relates to the call site of the
function.
