Rather than\nsetattr \u003e vmtruncate \u003e truncate, have filesystems call their truncate sequence\nfrom -\u003esetattr if filesystem specific operations are required. vmtruncate is\ndeprecated, and truncate_pagecache and inode_newsize_ok helpers introduced\npreviously should be used.\n\nsimple_setattr is introduced for simple in-ram filesystems to implement\nthe new truncate sequence. Eventually all filesystems should be converted\nto implement a setattr, and the default code in notify_change should go\naway.\n\nsimple_setsize is also introduced to perform just the ATTR_SIZE portion\nof simple_setattr (ie. changing i_size and trimming pagecache).\n\nTo implement the new truncate sequence:\n- filesystem specific manipulations (eg freeing blocks) must be done in\n the setattr method rather than -\u003etruncate.\n- vmtruncate can not be used by core code to trim blocks past i_size in\n the event of write failure after allocation, so this must be performed\n in the fs code.\n- convert usage of helpers block_write_begin, nobh_write_begin,\n cont_write_begin, and *blockdev_direct_IO* to use _newtrunc postfixed\n variants. These avoid calling vmtruncate to trim blocks (see previous).\n- inode_setattr should not be used. generic_setattr is a new function\n to be used to copy simple attributes into the generic inode.\n- make use of the better opportunity to handle errors with the new sequence.\n\nBig problem with the previous calling sequence: the filesystem is not called\nuntil i_size has already changed. This means it is not allowed to fail the\ncall, and also it does not know what the previous i_size was. Also, generic\ncode calling vmtruncate to truncate allocated blocks in case of error had\nno good way to return a meaningful error (or, for example, atomically handle\nblock deallocation).\n\nCc: Christoph Hellwig \u003chch@lst.de\u003e\nAcked-by: Jan Kara \u003cjack@suse.cz\u003e\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "1b061d9247f71cd15edc4c4c4600191a903642c0", "tree": "30d92ca82d8286e7a45fba108230ecd23e61673b", "parents": [ "7ea8085910ef3dd4f3cad6845aaa2b580d39b115" ], "author": { "name": "Christoph Hellwig", "email": "hch@lst.de", "time": "Wed May 26 17:53:41 2010 +0200" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Thu May 27 22:06:06 2010 -0400" }, "message": "rename the generic fsync implementations\n\nWe don\u0027t name our generic fsync implementations very well currently.\nThe no-op implementation for in-memory filesystems currently is called\nsimple_sync_file which doesn\u0027t make too much sense to start with,\nthe the generic one for simple filesystems is called simple_fsync\nwhich can lead to some confusion.\n\nThis patch renames the generic file fsync method to generic_file_fsync\nto match the other generic_file_* routines it is supposed to be used\nwith, and the no-op implementation to noop_fsync to make it obvious\nwhat to expect.
