Subject: Re: [PATCH 5/9] xfs: struct xfs_buf_log_format isn't variable sized.
Date: Wed, 20 Jun 2012 02:36:12 -0400 [thread overview]
Message-ID: <20120620063612.GB5467@infradead.org> (raw)

I like this patch with two minor nitpicks below. Given that it's a mostly
unrelated cleanup I'd also propagate it to the first patch in the
series.

I'd really move this calculation and the comment describing it into a
macro/inline in the header, next to the defintion of struct xfs_buf_log_format.
Also I'd probably rewrite the expressions as:
offsetoff(struct xfs_buf_log_format, blf_map) +
(blf->blf_map_size * sizeof(blf->blf_data_map[0]));
> /*

> +#define XFS_MIN_BLOCKSIZE_LOG 9 /* i.e. 512 bytes */
> +#define XFS_MAX_BLOCKSIZE_LOG 16 /* i.e. 65536 bytes */
> +#define XFS_MIN_BLOCKSIZE (1 << XFS_MIN_BLOCKSIZE_LOG)
> +#define XFS_MAX_BLOCKSIZE (1 << XFS_MAX_BLOCKSIZE_LOG)
> +#define XFS_MIN_SECTORSIZE_LOG 9 /* i.e. 512 bytes */
> +#define XFS_MAX_SECTORSIZE_LOG 15 /* i.e. 32768 bytes */
> +#define XFS_MIN_SECTORSIZE (1 << XFS_MIN_SECTORSIZE_LOG)
> +#define XFS_MAX_SECTORSIZE (1 << XFS_MAX_SECTORSIZE_LOG)
While I agree with the move of these constants, what does it have to do
with this patch?
