      "message": "dquot: move dquot initialization responsibility into the filesystem\n\nCurrently various places in the VFS call vfs_dq_init directly.  This means\nwe tie the quota code into the VFS.  Get rid of that and make the\nfilesystem responsible for the initialization.   For most metadata operations\nthis is a straight forward move into the methods, but for truncate and\nopen it\u0027s a bit more complicated.\n\nFor truncate we currently only call vfs_dq_init for the sys_truncate case\nbecause open already takes care of it for ftruncate and open(O_TRUNC) - the\nnew code causes an additional vfs_dq_init for those which is harmless.\n\nFor open the initialization is moved from do_filp_open into the open method,\nwhich means it happens slightly earlier now, and only for regular files.\nThe latter is fine because we don\u0027t need to initialize it for operations\non special files, and we already do it as part of the namespace operations\nfor directories.\n\nAdd a dquot_file_open helper that filesystems that support generic quotas\ncan use to fill in -\u003eopen.\n\nSigned-off-by: Christoph Hellwig \u003chch@lst.de\u003e\nSigned-off-by: Jan Kara \u003cjack@suse.cz\u003e\n"
