      "message": "fallocate should be a file operation\n\nCurrently all filesystems except XFS implement fallocate asynchronously,\nwhile XFS forced a commit.  Both of these are suboptimal - in case of O_SYNC\nI/O we really want our allocation on disk, especially for the !KEEP_SIZE\ncase where we actually grow the file with user-visible zeroes.  On the\nother hand always commiting the transaction is a bad idea for fast-path\nuses of fallocate like for example in recent Samba versions.   Given\nthat block allocation is a data plane operation anyway change it from\nan inode operation to a file operation so that we have the file structure\navailable that lets us check for O_SYNC.\n\nThis also includes moving the code around for a few of the filesystems,\nand remove the already unnedded S_ISDIR checks given that we only wire\nup fallocate for regular files.\n\nSigned-off-by: Christoph Hellwig \u003chch@lst.de\u003e\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n"
