Hi Andrew, We discussed this in madvise(REMOVE) thread - to add support for sys_punchhole(fd, offset, len) to complete the functionality (in the future). http://marc.theaimsgroup.com/?l=linux-mm&m=113036713810002&w=2 What I am wondering is, should I invest time now to do it ? Or wait till need arises ? My thought line is, I would add a generic_zeroblocks_range() function which would zero out the given range of pages and flush to disk. Use this as a default operation, if the filesystems doesn't provide a specific function to free up the blocks. Would this work ? Suggestions ?
