vfs: export lseek_execute() to modules For those file systems(btrfs/ext4/ocfs2/tmpfs) that support SEEK_DATA/SEEK_HOLE functions, we end up handling the similar matter in lseek_execute() to update the current file offset to the desired offset if it is valid, ceph also does the simliar things at ceph_llseek(). To reduce the duplications, this patch make lseek_execute() public accessible so that we can call it directly from the underlying file systems. Thanks Dave Chinner for this suggestion. [AV: call it vfs_setpos(), don't bring the removed 'inode' argument back] v2->v1: - Add kernel-doc comments for lseek_execute() - Call lseek_execute() in ceph->llseek() Signed-off-by: Jie Liu <[email protected]> Cc: Dave Chinner <[email protected]> Cc: Al Viro <[email protected]> Cc: Andi Kleen <[email protected]> Cc: Andrew Morton <[email protected]> Cc: Christoph Hellwig <[email protected]> Cc: Chris Mason <[email protected]> Cc: Josef Bacik <[email protected]> Cc: Ben Myers <[email protected]> Cc: Ted Tso <[email protected]> Cc: Hugh Dickins <[email protected]> Cc: Mark Fasheh <[email protected]> Cc: Joel Becker <[email protected]> Cc: Sage Weil <[email protected]> Signed-off-by: Al Viro <[email protected]>
