Subject: [PATCH] e4defrag: fix build when posix_fadvise is missing
|

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
