[RESEND PATCH v4] ext4: Annotate struct ext4_xattr_inode_array with __counted_by()

Add the __counted_by compiler attribute to the flexible array member inodes to improve access bounds-checking via CONFIG_UBSAN_BOUNDS and CONFIG_FORTIFY_SOURCE. Remove the now obsolete comment on the count field. In ext4_expand_inode_array(), use struct_size() instead of offsetof() and remove the

[PATCH 2/3] kprobes: Cleanup the config comment

The CONFIG_KPROBES_ON_FTRACE #if/#else/#endif section is small and doesn't nest additional #ifdefs so the comment is useless and should be removed, but the __ARCH_WANT_KPROBES_INSN_SLOT and CONFIG_OPTPROBES() nest is long, it is better to add comment for reading. Signed-off-by: Jinjie Ruan --- k

[PATCH 0/2][next] UAPI: net/sched - cxgb4: Fix -Wflex-array-member-not-at-end warning

Small patch series aimed at fixing a -Wflex-array-member-not-at-end warning by creating a new tagged struct within a flexible structure. We then use this new struct type to fix a problematic middle-flex-array declaration in a composite struct. Gustavo A. R. Silva (2): UAPI: net/sched: Use __stru

[PATCH 1/2][next] UAPI: net/sched: Use __struct_group() in flex struct tc_u32_sel

Use the `__struct_group()` helper to create a new tagged `struct tc_u32_sel_hdr`. This structure groups together all the members of the flexible `struct tc_u32_sel` except the flexible array. As a result, the array is effectively separated from the rest of the members without modifying the memory l
