[PATCH 03/21] xfs: hoist inode flag conversion functions to libxfs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Darrick J. Wong <djwong@xxxxxxxxxx>

Hoist the inode flag conversion functions into libxfs so that we can
keep them in sync.  Do this by creating a new xfs_inode_util.c file in
libxfs.
