To: linux-fsdevel
This series of patches is a cleanup of disk quotas. It:
* moves quota code into a separate directory,
* replaces old uppercase quota calls in filesystems with new lowercase
equivalents,
* removes some superfluous inlines,
* other coding style/readability fixes.

Looking over this again I think the vfs_ names are a really bad choice. The normal use for vfs_ are higher level functions that call into specific filesystems, which these aren't really.

What about just > striping out that vfs_ prefix first? Actually, these vfs_dq_ functions are usually just wrappers like: static inline void vfs_dq_init(struct inode *inode) { BUG_ON(!inode->i_sb); if (sb_any_quota_active(inode->i_sb) && !IS_NOQUOTA(inode)) inode->i_sb->dq_op->initialize(inode, -1); } where ->initialize either leads to a filesystem specified callback or to generic quota init function. So this seems to reasonably match your description above... But if this still has not convinced you ;), I can change all these quota functions to have names starting with dq_. That should not clash with anything else. But I'm not very enthusiastic about this change (cleanups are so boring...).

Changing away from the weird uppercase names defintively is a good thing. Although for the ops inside the filesystem it might be better to just call into the lowlevel operation instead of the vfs_ helper as we know what we want, no? ^ permalink raw reply [flat|nested] 23+ messages in thread

Yes, filesystem knows what it wants but the vfs_ helpers are there so that every filesystem does not have to implement the same checks (usually checking whether quota is enabled etc)...
