At the moment there is just a rough idea，test a portion of the data to decide whether to compress it before performing a full compression. It may need more test. Any other suggestions? In my consider, the non-compress flag has a higher priority than the compressed flag. 1. the same extension name cannot not appear in both compress and non-compress extension at the same time， check this in mount process. 2. If the compress extension specifies all files, the types specified by the non-compress extension will be treated as special cases and will not be compressed. 3. If the non-compress extension specifies all files, should not specifies any compress extension, check in mount process too. Any other suggestions? Thanks. --===============0030318180835187861== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline --===============0030318180835187861== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ Linux-f2fs-devel mailing list Linux-f2fs-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linux-f2fs-devel --===============0030318180835187861==--
