From: Hou Tao <houtao1@huawei.com> Hi, The simple patchset aims to replace GFP_ATOMIC in bpf_event_entry_gen(). These two patches in the patchset were preparatory patches in "Fix the release of inner map" patchset [1] and are not needed for v2, so re-post it to bpf-next tree. Patch #1 reduces the scope of rcu_read_lock when updating fd map and patch #2 replaces GFP_ATOMIC by GFP_KERNEL. Please see individual patches for more details. Comments are always welcome.
