Well some bits can be moved up. Here's my grand plan which I plan to implement once I get some time for it (or let someone else do if they beat me): - generic_segment_checks goes to fs/read_write.c before caling into the filesystem - dito for vfs_check_frozen - generic_write_checks is a suitable helper already - dito for remove_suid - dito for file_update_time - after that there's not a whole lot left in generic_file_aio_write, except for direct I/O handling which will probably be very fs-specific if you have your own buffered I/O code generic_file_buffered_write is an almost trivial wrapper around what's ->perform_write in Nick's earlier patches and a helper for the syncing activity. > > But with fuse being the only user, it's not a huge issue duplicating > some code. > > Nick, were there any other candidates, that would want to use such an > interface in the future? > > Thanks, > Miklos > - > To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html ---end quoted text--- - To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
