Subject: [PATCH] configure: add check for fallocate
|
||
|
|
|
||
|
|
We need to check for fallocate() rather than just linux/falloc.h +
|
||
|
|
FALLOC_FL_PUNCH_HOLE since in uClibc we've got both but still not
|
||
|
|
fallocate() itself since it's only implemented in newer unreleased
|
||
|
|
versions.
|
||
|
|
|
||
|
|
Status: sent upstream.
