Subject: [PATCH] e4defrag: fix build when posix_fadvise is missing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
uClibc declares posix_fadvise() even when the architecture does not provide
one. The static posix_fadvise() signature is not compatible with POSIX. Rename
the internal implementation to fix this. Fixes the following build failure
when building against uClibc:
e4defrag.c:189:2: warning: #warning Using locally defined posix_fadvise interface. [-Wcpp]
e4defrag.c:203:12: error: conflicting types for posix_fadvise
Patch status: sent upstream
(http://marc.info/?l=linux-ext4&m=138857218522054&w=2)
