There are no functional changes to the XFS code itself. Thanks.

I consider the context it adds to cscope searches a damn good reason for keeping it. > Why not just > do something like > > for i in xfs_*; do j=$(echo $i | sed 's/^xfs_//'); git mv $i $j; done > > to get rid of the silly "xfs_" prefix that adds nothing? Because that then kills context that is actually useful in cscope searches. That is, every filesystem has the file "inode.c", "super.c", etc and so you can't tell from the cscope searchs which filesystem function calls belong to. Duplicate name spaces are evil, and we have a lot of them in the filesystem tree - if they all had explicit namespacing like XFS does, then the world would be a better place. ;) > You could use the bytes you save to rename "qm.c" to "quota_manager.c" > instead.

The name of the file reflects the namespace of the code inside the file itself. e.g. to use the xfs_qm.c as an example: $ grep ^xfs_qm_ fs/xfs/xfs_qm.c xfs_qm_destroy( xfs_qm_hold_quotafs_ref( xfs_qm_rele_quotafs_ref( xfs_qm_unmount( xfs_qm_mount_quotas( xfs_qm_unmount_quotas( xfs_qm_dqflush_all( xfs_qm_detach_gdquots( xfs_qm_dqpurge_int( xfs_qm_dqpurge_all( xfs_qm_dqattach_one( xfs_qm_dqattach_grouphint( xfs_qm_dqattach_locked( xfs_qm_dqattach( xfs_qm_dqdetach( xfs_qm_sync( xfs_qm_init_quotainfo( xfs_qm_destroy_quotainfo( xfs_qm_list_init( xfs_qm_list_destroy( xfs_qm_qino_alloc( xfs_qm_reset_dqcounts( xfs_qm_dqiter_bufs( xfs_qm_dqiterate( xfs_qm_quotacheck_dqadjust( xfs_qm_get_rtblks( xfs_qm_dqusage_adjust( xfs_qm_quotacheck( xfs_qm_init_quotainos( xfs_qm_dqreclaim_one(void) xfs_qm_shake_freelist( xfs_qm_shake_scan( xfs_qm_shake_count( xfs_qm_dqalloc_incore( xfs_qm_write_sb_changes( xfs_qm_vop_dqalloc( xfs_qm_vop_chown( xfs_qm_vop_chown_reserve( xfs_qm_vop_rename_dqattach( xfs_qm_vop_create_dqattach( So there is a certain methodic sanity to the naming convention that is not immediately obvious from just looking at the file names, and that's a good reason not to change them.

Because that then kills context that is actually useful in cscope searches.

Umm. I suggest you start learning to use the tools you have, rather than blame your inability to use them for then making crap decisions in file naming. Read up on the "-pN" thing to cscope. So here's a trick of the day: export CSCOPEOPTIONS=-p2 or something like that. And stop using crap to excuse bad decisions.

If you're passing judgement on the XFS filenaming convention, then don't blame me - way before my time. e.g. the two initial XFS commits from 29 October, 1993 show exactly the same names as we currently use: http://oss.sgi.com/cgi-bin/gitweb.cgi?p=archive/xfs-import.git;a=commitdiff;h=67e682e44dd02a2a0efaa0ed2579894325010a85 http://oss.sgi.com/cgi-bin/gitweb.cgi?p=archive/xfs-import.git;a=commitdiff;h=ec2b385b4b79e3967e1e0480fb1863ba029f6c30 So perhaps you might want to go hunt down the original XFS developers. They'd probably just laugh at you, though. Regardless, changing the filenames now is a bad idea. Plenty of people are familiar with what they mean and what they contain, and changing them just means everyone has to relearn where stuff is. We lose the simple solution to the question "what file does that function exist in" and deciding where to put new code becomes harder because it's not as clear what the overall scope of each file is supposed to be. It will also make code archeology during bug triage harder as well. That doesn't improve anything for anyone in the short term - it will only slow us down. And in the long term, a major rename makes things like backports to stable kernels harder, more time consuming and more error prone due to the extra transformations that need to take place for each patch. That's two strikes. Then there is also the userspace tools that share a bunch of the kernel code that we have to keep in sync. Hence renaming the kernel files means we'll make a bunch of work for ourselves in userspace as well to keep that in sync. Strike Three. So really, I can't see any good reason to change the XFS file names. > Read up on the "-pN" thing to cscope. I learnt about that in 2002. However, if you ever used cscope with the -pN option on a source tree with long verbose filenames (like you suggest) and functions on a 80-90 column terminal, you'd understand that these shift the code context output (the most important bit of the cscope output) so far across the terminal that it line wraps 3 or 4 times and is completely unreadable..... > So here's a trick of the day: > > export CSCOPEOPTIONS=-p2 > > or something like that. Sure. You need to wrap it in an alias because cscope doesn't have a magic environment variable or config file to set default options. Of course, the obvious logical extension of that is to then hook up a script to PROMPT_COMMAND or aliasing cd/pushd/popd (or cwdcmd for tcsh) so that $CSCOPEOPTIONS changes automatically depending on the source tree you are currently working in. That would require learning a bit about the tools you use every day, though.
