Thus filesystems which don't need it save 2 pointers in their inodes (would be 3 after we add project quota support into generic quota). I have patches to move inode->i_data.private_list into filesystem private part of the inode which is going to save another 2 pointers using the same mechanism. However I didn't want to mix those in. The patch series also contains a change to quotactl so that each filesystem can set quota types it supports. This is in the end unrelated change (originally it was necessary for i_dquot moving but in the end I changed things so that it's not anymore). I can move that into a separate series but I was somewhat reluctant to do that since that would mean another 6 one-line patches to the same files we are changing here... If noone has any objections, I'd like to queue this series into my tree for the next merge window. For that I'd prefer to get acks from affected fs maintainers (the changes are pretty trivial and I don't feel it's a must but still I'd prefer fs maintainers to ack they are aware of the changes). Honza Changes since v1: * Inode field names are now named enum * Quota type masks now have names like QTYPE_MASK_{USR|GRP|PRJ} instead of opencoding shifts. _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
