[PATCH] sctp: Replace zero-length array with DECLARE_FLEX_ARRAY() helper

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


Zero-length arrays are deprecated and we are moving towards adopting
C99 flexible-array members instead. So, replace zero-length array
declaration in struct fid with the new DECLARE_FLEX_ARRAY()
helper macro.

This helper allows for a flexible-array member in a union.
