From: Hou Tao <houtao1@huawei.com> Hi, The simple patch set aims to replace GFP_ATOMIC by GFP_KERNEL in bpf_event_entry_gen(). These two patches in the patch set 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. Change Log: v3: * patch #1: fallback to patch #1 in v1. Update comments in bpf_fd_htab_map_update_elem() to explain the reason for rcu_read_lock() (Alexei) v2: https://lore.kernel.org/bpf/20231211073843.1888058-1-houtao@huaweicloud.com/ * patch #1: add rcu_read_lock/unlock() for bpf_fd_array_map_update_elem as well to make it consistent with bpf_fd_htab_map_update_elem and update commit message accordingly (Alexei) * patch #1/#2: collects ack tags from Yonghong v1: https://lore.kernel.org/bpf/20231208103357.2637299-1-houtao@huaweicloud.com/ [1]: https://lore.kernel.org/bpf/20231107140702.1891778-1-houtao@huaweicloud.com/ Hou Tao (2): bpf: Reduce the scope of rcu_read_lock when updating fd map bpf: Use GFP_KERNEL in bpf_event_entry_gen() kernel/bpf/arraymap.c | 2 +- kernel/bpf/hashtab.c | 6 ++++++ kernel/bpf/syscall.c | 4 ---- 3 files changed, 7 insertions(+), 5 deletions(-)
