Commit Message

Chandan Babu R Jan. 29, 2020, 4:59 a.m. UTC
This commit changes xfs_attr_leaf_newentsize() to explicitly accept name and
value length instead of a pointer to struct xfs_da_args. The next commit will
need to invoke xfs_attr_leaf_newentsize() from functions that do not have
a struct xfs_da_args to pass in.

Any reason not to just pass the geo here rather than the mount?
Otherwise looks fine to me.

Sorry, I noticed this message now.

You are right. I will change the first argument to be attr geometry pointer.
