Subject: [PATCH][next] exportfs: Replace zero-length array with DECLARE_FLEX_ARRAY() helper
Date: Sat, 3 Sep 2022 00:08:51 +0100 [thread overview]
Message-ID: <YxKNA/3add4wxI3R@work> (raw)
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.
