  "message": "ext3: support large blocksize up to PAGESIZE\n\nThis patch set supports large block size(\u003e4k, \u003c\u003d64k) in ext3 just enlarging\nthe block size limit.  But it is NOT possible to have 64kB blocksize on\next3 without some changes to the directory handling code.  The reason is\nthat an empty 64kB directory block would have a rec_len \u003d\u003d (__u16)2^16 \u003d\u003d\n0, and this would cause an error to be hit in the filesystem.  The proposed\nsolution is treat 64k rec_len with a an impossible value like rec_len \u003d\n0xffff to handle this.\n\nThe Patch-set consists of the following 2 patches.\n  [1/2]  ext3: enlarge blocksize\n         - Allow blocksize up to pagesize\n\n  [2/2]  ext3: fix rec_len overflow\n         - prevent rec_len from overflow with 64KB blocksize\n\nNow on 64k page ppc64 box runs with this patch set we could create a 64k\nblock size ext3, and able to handle empty directory block.\n\nSigned-off-by: Takashi Sato \u003csho@tnes.nec.co.jp\u003e\nSigned-off-by: Mingming Cao \u003ccmm@us.ibm.com\u003e\nCc: \u003clinux-ext4@vger.kernel.org\u003e\nAcked-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
