This means we lose 1/2 of the possible range\nof timestamps (lopping off 68 years before unix timestamp overflow -\nnow only 30 years away :-) to handle the extremely rare case of setting\ntimestamps into the distant past.\n\nIf we are only interested in fixing the underflow case, we could just\nlimit the values to 0 instead of storing negative values.  At worst this\nwill skew the timestamp by a few hours for timezones in the far east\n(files would still show Jan 1, 1970 in \"ls -l\" output).\n\nThat said, it seems 32-bit systems (mine at least) allow files to be set\ninto the past (01/01/1907 works fine) so it seems this patch is bringing\nthe x86_64 behaviour into sync with other kernels.\n\nOn the plus side, we have a patch that is ready to add nanosecond timestamps\nto ext3 and as an added bonus adds 2 high bits to the on-disk timestamp so\nthis extends the maximum date to 2242.\n\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

While\ntrying to fix them, it seems quite confusing in the ext3 code where some\nblocks are filesystem-wide blocks, some are group relative offsets that need\nto be signed value (as -1 has special meaning).  So it seem saner to define\ntwo types of physical blocks: one is filesystem wide blocks, another is\ngroup-relative blocks.  The following patches clarify these two types of\nblocks in the ext3 code, and fix the type bugs which limit current 32 bit ext3\nfilesystem limit to 8TB.\n\nWith this series of patches and the percpu counter data type changes in the mm\ntree, we are able to extend exts filesystem limit to 16TB.\n\nThis work is also a pre-request for the recent \u003e32 bit ext3 work, and makes\nthe kernel to able to address 48 bit ext3 block a lot easier: Simply redefine\next3_fsblk_t from unsigned long to sector_t and redefine the format string for\next3 filesystem block corresponding.\n\nTwo RFC with a series patches have been posted to ext2-devel list and have\nbeen reviewed and discussed:\nhttp://marc.theaimsgroup.com/?l\u003dext2-devel\u0026m\u003d114722190816690\u0026w\u003d2\n\nhttp://marc.theaimsgroup.com/?l\u003dext2-devel\u0026m\u003d114784919525942\u0026w\u003d2\n\nPatches are tested on both 32 bit machine and 64 bit machine, \u003c8TB ext3 and\n\u003e8TB ext3 filesystem(with the latest to be released e2fsprogs-1.39).  Tests\nincludes overnight fsx, tiobench, dbench and fsstress.\n\nThis patch:\n\nDefines ext3_fsblk_t and ext3_grpblk_t, and the printk format string for\nfilesystem wide blocks.\n\nThis patch classifies all block group relative blocks, and ext3_fsblk_t blocks\noccurs in the same function where used to be confusing before.  Also include\nkernel bug fixes for filesystem wide in-kernel block variables.  There are\nsome fileystem wide blocks are treated as int/unsigned int type in the kernel\ncurrently, especially in ext3 block allocation and reservation code.

The basic idea is allocating the 1st block in the existing\nway, and attempting to allocate the next adjacent blocks on a best effort\nbasis.

The break ups are:\n\n [patch 1] Adding map multiple blocks at a time in ext3_get_blocks()\n [patch 2] Extend ext3_get_blocks() to support multiple block allocation\n [patch 3] Implement multiple block allocation in ext3-try-to-allocate\n (called via ext3_new_block()).\n [patch 4] Proper accounting updates in ext3_new_blocks()\n [patch 5] Adjust reservation window size properly (by the given number\n of blocks to allocate) before block allocation to increase the\n possibility of allocating multiple blocks in a single call.\n\nTests done so far includes fsx,tiobench and dbench.
