I wonder if it wouldn't have been simpler to keep the original function name and change its behavior to that of xfs_attr_rmtval_unmap(). Unless the function name change makes the logic change more clear for the future users??? > fs/xfs/libxfs/xfs_attr_remote.c | 42 ----------------------------------------- > fs/xfs/xfs_trace.h | 1 - > 2 files changed, 43 deletions(-) > > diff --git a/fs/xfs/libxfs/xfs_attr_remote.c b/fs/xfs/libxfs/xfs_attr_remote.c > index a0e79db..0cc0ec1 100644 > --- a/fs/xfs/libxfs/xfs_attr_remote.c > +++ b/fs/xfs/libxfs/xfs_attr_remote.c > @@ -734,48 +734,6 @@ xfs_attr_rmtval_invalidate( > } > > /* > - * Remove the value associated with an attribute by deleting the > - * out-of-line buffer that it is stored on. > - */ > -int > -xfs_attr_rmtval_remove( > - struct xfs_da_args *args) > -{ > - xfs_dablk_t lblkno; > - int blkcnt; > - int error = 0; > - int done = 0; > - > - trace_xfs_attr_rmtval_remove(args); > - > - error = xfs_attr_rmtval_invalidate(args); > - if (error) > - return error; > - /* > - * Keep de-allocating extents until the remote-value region is gone. > - */ > - lblkno = args->rmtblkno; > - blkcnt = args->rmtblkcnt; > - while (!done) { > - error = xfs_bunmapi(args->trans, args->dp, lblkno, blkcnt, > - XFS_BMAPI_ATTRFORK, 1, &done); > - if (error) > - return error; > - error = xfs_defer_finish(&args->trans); > - if (error) > - return error; > - > - /* > - * Close out trans and start the next one in the chain. > - */ > - error = xfs_trans_roll_inode(&args->trans, args->dp); > - if (error) > - return error; > - } > - return 0; > -} > - > -/* > * Remove the value associated with an attribute by deleting the out-of-line > * buffer that it is stored on.

I thought about this, but then decided against it. Really what's happening is that the original function disappears across patches 13 and 14, and I wanted to keep those patches focused on the state machine rather than lumping the helpers in with it. > > Unless the function name change makes the logic change more clear > for the future users??? I think they are about equivalent myself. But the name difference helps the old function to stick around until it is completely phased out. If folks feel strongly though, please chime in :-) Thanks for the reviews! I know it's a lot!
