Subject: [PATCH v6 net-next 08/15] net: allow ndo_get_stats64 to return an int error code
From: Vladimir Oltean <vladimir.oltean@....com>
Some drivers need to do special tricks to comply with the new policy of
ndo_get_stats64 being sleepable. For example, the bonding driver, which
derives its stats from its lower interfaces, must recurse with
dev_get_stats into its lowers with no locks held. But for that to work,
it needs to dynamically allocate some memory for a refcounted copy of
its array of slave interfaces (because recursing unlocked means that the
original one is subject to disappearing). And since memory allocation
can fail under pressure, we should not let it go unnoticed, but instead
propagate the error code.
This patch converts all implementations of .ndo_get_stats64 to return
int, and propagates that to the dev_get_stats calling site. Error
checking will be done in further patches.
Signed-off-by: Vladimir Oltean <vladimir.oltean@....com>
---
Changes in v6:
Remove the unused "int err" from __bond_release_one and add it in the
patch it belongs to.
Changes in v5:
None.
Changes in v4:
Patch is new (Eric's suggestion).
