Subject: [PATCH V2 1/2] xfsprogs: Pass xattr name and value length explicitly to xfs_attr_leaf_newentsize
Date: Wed, 15 Jan 2020 18:24:49 +0530 [thread overview]
Message-ID: <20200115125450.22782-1-chandanrlinux@gmail.com> (raw)
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.

Changelog:
V1 -> V2:
1. Use convenience variables to reduce indentation of code.
